Is 8.2 grain ok for the HW30S?
What is the maximum grain one would recommend to ensure smooth operation and longevity of the rifle?

I don't know what the maximum grain would be but, l do know that my three HW30S' and my Beeman R7 prefer the 7.44 gr. AA's.

I have had great accuracy and pretty good spring longevity with AA Field at 8.4 grains. I wouldn't go any heavier, however. The latest batch that I received seem to be from an inferior lot so I have switched over to JSB Express at 7.9 gr. They work almost as well as the old AADF.
Definitely DON'T try heavy pellets with a head size that is too large. I have gotten some Baracudas and Premiers stuck in the barrel before.
-
I've never shot anything over 8.44 gr. My Beeman R7 .177 prefers Air Arms 7.87 gr.
Personally I don't shoot Crosman pellets in any of my Weihrauch rifles.

There is no maximum grain. Around 8 will give you about the best trajectory at that power level. If you shoot heavier, it would be easier on the mainspring, but it doesn't matter much. Don't dry fire it.
-
My three Hw30s are most efficient and usually most accurate with 7.33 JSB or the AA clones. Efficiency is a good indication of what's easy on the gun. It's not necessarily the most accurate. There's times where 8.44 Exacts or 8.64 FTTs are more accurate. It depends a lot on the tins in hand. A good fitting tin of 8.44s will be more accurate than a poor fitting tin of 7.33s.
Typically with springers heavy for caliber pellets tend to induce more piston bounce which shortens spring life. I normally run 7.33s and 8.44s in my 30s depending on which is more accurate at the moment. The 7.33s make about a half pound more energy which tells you the gun is working more smoothly internally. Incidentally more smoothly helps with accuracy. Rebounding pistons from less efficient heavy weights can induce pressure pulses that disrupt accuracy.
All of my 177 Weihrauchs haves been most efficient with 8.44 grain pellets or lighter. Also fit has a bit of effect as well. A very tight pellet may decrease efficiency more than a loose fitting heavy pellet. Bottom line stay around 8 grains or under in your 30 and you'll be fine. You're gonna have to replace the spring eventually anyway. Use whatever you like but staying under 9 will help you get the most out of the spring. And for goodness sakes don't dry fire it because that will hurt the spring infinitely more than heavier pellets.
-
As above, I now use mostly 7.33 JSBs in both of my two HW30s, but they've also done well with a variety of heavier pellets in the 8 plus range. Nothing heavier, though. I just find that the 7.33s are a good match for the HW30 power level and plenty accurate.
-
I've had the most luck in my HW30 with 7.87 grain H&N Finale Match Light. Air Arms 7.87's shoot well too.

I also have found the AA Falcon 7.33 grain pellet the most accurate in my HW30S .... followed by the JSB 7.33 grain pellet ;).

I don't care for Crosman pellets either. I used to use them a lot until about summer 2018. My problem with them is two-fold. First is the lack of QC. Unless they've improved the 177 Walmart CPHP seem to vary quite a bit in size within the tin. Heck I had to return two out of three tins once because they had 22s mixed in. If you stay away from their economy lines, Brands like JSB, RWS and H&N stay closer sized within a tin. Not always perfect but markedly closer. Thus they typically have less radical flyers.
My second gripe is that Crosman uses a lot more antimony in their pellets than other brands. This makes them harder than other brands. It helps prevent shipping damage. The problem with hard lead is you either have to use it all the time or not at all.
Barrel seasoning or (fouling in a good way) is very important to accuracy. It can take a hundred sometimes a thousand shots to season a brand new or newly scrubbed and polished barrel. Shooting six hard lead Crosmans can almost undo all that soft lead fouling or seasoning. The hard lead scrapes it right out. If you continually shoot Crosman pellets or more Crosman than soft lead brands the barrel becomes seasoned with hard lead.
Soft lead can't clear the hard lead for obvious reasons. Now the expensive brand soft lead pellets just won't print as good as they should. At least until all the hard lead is literally scrubbed out and the barrel goes through the whole seasoning process again with soft lead. Which depending on the barrel can takes hundreds of expensive pellets. BTW soft lead pellets won't ever excessively foul a barrel. Crosman will. I haven't needed to clean any of my personal gun barrels since switching to soft lead brands. Some of these guns have over 30k shots on them.
Anyway between the inconsistent QC (flyers), the hard lead screwing up my accuracy with other brands and additional maintenance, I've decided not to use Crosman pellets. I can afford better pellets, so I shoot better pellets. I get more consistent accuracy from them and I'm willing to pay for it.
You'd simply be wasting money using expensive soft lead pellets through a Crosman seasoned barrel because they won't print as good as they could. If you're happy with the accuracy you get from Crosmans, stay with them and maybe just clean the barrel every couple thousand rounds to keep them shooting well.

Return them if you can - they are cheap - yes - but not consistant in size plus the lead alloy.
The Crosman pellets are made with increased Antimony in the lead alloy.
Crosman uses a harder lead alloy to prevent their pellets from distorting though normal storage and handling.
This makes then harder than lead but also deposit harder material in the barrel over time.

"What is wrong with crossman pellets? I just ordered a whole bunch."
Back when Crosman was offering their die lot marked and dated 7.9 grain Premiers in the 1250 count cardboard box were the most accurate pellets for my HW springers. A while back Crosman discontinued the "1250 count boxed Premiers" and only the 500 count tims have bee available since.
I tried the Crosman Premier Hollow Points variety "from the tin" and found them to have rather small heads which didn't fit my .177 leade snugly giving mediocre accuracy...........

A few years ago the "Crosmans from the tin" occasionally came packed with "swarf and gunge" so I didn't test them for very long, perhaps Crosman has "cleaned up their act" and they may work well with your particular gun.......

Thanks everyone for the education.
Regarding the antimony/crossman pellets, will it damage the rifle or is it more an accuracy thing (which I care a lot about too btw)?
What is swarf and gunge?

Definitely DON'T try heavy pellets with a head size that is too large. I have gotten some Baracudas and Premiers stuck in the barrel before.
The Baracudas were 10.67 and the Premiers were 10.5.
Baracudas are great pellets for powerful guns that can make use of them... not so much for a svelte little HW 30.
Premiers have a bad rep among a lot of airgunners who shoot more expensive guns. IME they are clearly not as consistently made as JSB or RWS, for example. The box I had was especially bad and had absurd variations in head size. No gun I have ever owned (and I have had many come and go) shot them well.
-
fine chips or filings of stone, metal, or other material produced by a machining operation.
"a curl of metal swarf"
Gunge - informal British
a sticky, viscous, and unpleasantly messy material.
Thanks for the information on the CPHPs and the HW30S which is on my dreamlist next.
-
I still have 5 boxes of CPL from 2017 for my HW95 Hybrid ;).
- The 7.9 grain pellets are the best that I've found to date and when they're gone .... :P.
-
The ftt greens seem pretty consistently sized. The one's I've had. 5.25 grains.

I frequently shoot JSB 10.3s in my R7s as they deliver great accuracy and have put many thousands down the barrel.

I would suggest you buy a sampler of different pellets. There is a fellow in the classifieds that will put together a sampler pack of pellets that you choose. You can see what head sizes and pellet weights your barrel likes. ;)

Barrel seasoning or (fouling in a good way) is very important to accuracy. It can take a hundred sometimes a thousand shots to season a brand new or newly scrubbed and polished barrel. Shooting six hard lead Crosmans can almost undo all that soft lead fouling or seasoning. The hard lead scrapes it right out. If you continually shoot Crosman pellets or more Crosman than soft lead brands the barrel becomes seasoned with hard lead.

Thanks for posting this. When I bought my Silent Cat I ordered 1000 Crosmans with it. My R9 is supposed to arrive today with 2000 JSB and H&N pellets. So now I'll shoot all the remaining 700 Crosmans through the Silent Cat, and then clean it. Would it be OK to use a brass bristle brush that one time to do the scrubbing?

Glenn I wish I could give you an answer. I've bronze brushed all my Weihrauch barrels that have had or may have had Crosman pellets run through them. It's also a part of every Weihrauch tune I've done on used guns since I don't know the guns history.
I can't vouch for the Silent Cat's barrel. I'm not sure of the integrity of the material. If it's a steel barrel the bronze brush should be fine.
When in doubt I'm a big proponent of JB bore paste. Perhaps a few tight patches of that though the barrel several times will remove the hard lead. Just expect the accuracy to be terrible until the bore is seasoned. It can take quite a few pellets to season a freshly scrubbed bore. Every barrel is different even among the same model rifle. This is all a pita and why a stay with soft lead pellets. So far I haven't cleaned a bore on a gun that's used solely soft lead pellets. It's a little more expensive but the results and reduced maintenance is worth it to me.
Good luck to you.

Thanks!

When I used the boxed hard lead Crosman Premiers one of the main "negatives" was the fact that the lead/antimony alloy would foul the bore rather quickly and the fouling was a "BEAR" to remove. My brother's .177 R9 bore got so fouled that the pellet lead packed in the rifling to the point that the rifling lands were completely buried and all multiple pulled patches did was to polish the fouling. To remedy the situation my brother soaked the bore witgh Hoppes #9 for an hour, then used a .177 brass brush to successfully remove the fouling.
A properly fitting die lot marked and dated boxed Crosman Premiers (each box had a few that were undersized) were the most accurate pellet from our R9s so we started lubing our pellets to prevent the lead fouling from "packing like solder" in the rifling. First we tried FP10 which was used frequently by some at that time and it did minimize the bore fouling and the fouling was rather easily removed with a few pulled patches. The issue for us and the FP10 was that lubed Premiers stored in our pellet pouches would oxidize with a "goopy gungy" coating that fouled our bores even quicker. The next "pellet lube" we tried was aerosol Slick50 One Lube and it worked perfectly with proper application. Bore fouling was minimized, bore cleaning was easy using pulled patches and the pellet remained "corrosion free".
Slick50 OneLube will diesel if it gets into the pellet skirt so we would simply spritz a small amount in on the bottom of a dedicated pan, spread a film of lube on the pan, dump in a box of CPs, gently stir the pellets to distribute a film only on the pellet rifling surfaces, then dump the lubed pellets in the pellet pouch..........
(https://i.imgur.com/MkH4ZjP.jpg)(https://i.imgur.com/Pmbly2D.jpg)
I used to tune my .177 R9 to shoot my hard lead CPs at 900-910fps plus I didn't sort my pellets prior to shooting. I have a suspicion that when I loaded a "loose fitter" and shot it the rifling would shave a bit of lead at the choke and then the following pellet would pack the "shavings" into the rifling so perhaps this was part of the "fouling issues" I had when shooting unlubed CPs. After a while I presorted my CPLs before shooting by dropping them into the leade and visually noting how how it sat before pushing it home. If the pellet visually dropped too deep into the leade it was shaken out and another was dropped. If it visually sat at the normal height it would be pushed flush with the pivot block and shot. I can tell from experience that both my brother and I would probably have an "unexplained" flier if a "pee-wee" that dropped too deep was shot.
The .177 R7/HW30 doesn't shoot pellets near the velocity of the R9/HW95 so perhaps bore fouling wouldn't be an issue however dry hard lead Crosman pellets are "known bore foulers".
-
Thanks Ed,
I'll wash and lube my boxed CPL's with T-9 as recommended by Hector.
Since I have many guns, the positive is my 5 boxes (6,000 pellets) should last me a few years of more ... 8).
In the mean time you can determine what my next HW95 pellet should be :D.

I still have about 6 boxes of die lot marked and dated CPLs left but a while back I started looking for alternatives since the boxed CPLs became "unobtanium". So far the two brands "in the running" are the 8.4 grain 4.52mm Air Arms domes and the 8.64 H&N Field Target Trophy..........

Thanks again Ed,
I have many tins of 8.44 JSB's and H&N 8.64's, but haven't bought the AA 8.44's.
However, in my shooting have noticed AA version of JSB's seem to be a whisker more accurate.

Before trying the 4.52mm 8.4gr Air Arma domes I bought several tins of supposedly 4.52mm 8.4 grain JSB Exacts and found the head sizes to be "all over the place". I also bought a tin of 4.50mm labeled JSB Exacts and compared the two tins. There were Exacts from the supposedly 4.52mm tins that had head sizes smaller than those from the 4.50mm tin and visa versa. I always found that the supposedly 4.52mm Exacts were "loose fitters" in the leade of my .177 R9 however this was driven home by a THAGC field target match a few years ago. During the match I had a "dry fire" and was annoyed at myself for neglecting to load a pellet for the shot. Well, later in the match I had ANOTHER dryfire and was very annoyed at my absentmindedness to "forget" loading a pellet the second time. As the match continued I reloaded another supposedly 4.52mm Exact but when I was relatching the barrel I SAW the JSB flip out of the leade before "latch-up". LOL...I wasn't previously forgetting to insert pellets, the "loosies" were flipping out of the leade before the actual "latch-up"!.
That fiasco prompted me to actually check the pellet head sizes of the remaining 9 tins of supposedly 4.52mm Exacts. Here are the results..........
JSB Exacts:
(https://i.imgur.com/udeSRar.jpg)(https://i.imgur.com/5vGMBDx.jpg)
AA Domes:
I ended up selling those tins of Exacts "fer cheap" however later I tried some 4.52mm 8.4 grain Air Arms domes and found that even though they were produced in the same JSB plant (rumor claim using Air Arms supplied dies) and found that for whatever reason the AA dome head sizes were more consistent and closer to the advertised 4.52mm...........

Measuring pellet heads really isn't an "exact science" as pertaining to the "1/100th of mm" but I've developed a "satisfactory for my purposes" method that at least gives consistent accuracy based on the actual caliper reading. I'm not very concerned with the exact "third metric place reading", just that all pellets start with a consistent head size. 1st I needed a digital caliper with pretty good resolution and testing the accuracy with a micrometer test bar..........
(https://i.imgur.com/yQq4ijE.jpg)(https://i.imgur.com/TEQu1of.jpg)
The procedure.........
(https://i.imgur.com/SplzdQ7.jpg)(https://i.imgur.com/JkExcWJ.jpg)(https://i.imgur.com/Wp4LITY.jpg)
There are those that like to use "holes in a plate" to sort/size their pellets but I'm not convinced that this is any more accurate than my "caliper method" because I've found that pellet heads aren't always "perfectly round" finding that some .177 pellets were as much as .02mm out of round which was verified using multiple measurements at opposing sides of the pellet heads........
Holes in a plate...........
(https://i.imgur.com/p2DhzaZ.png)
Measuring pellets is very tedious but if the pellet heads are large enough to be "swaged to size" when pressing them into the leade then I really don't think that that the "second decimal point" is very important (LOL, I could be wrong). To eliminate measuring pellet heads to determinr "ovality" (two measurement for each pellet plus a few more "verifying measurement") I made up pellet sizers for my particular break barrels. My newer .177 HW95 has a smaller leade than my older .177 Beeman R9 so I used to size pellet heads to 4.48mm for the HW95 and 4.52mm for the Beeeman R9. Later I found that a 4.50mm "measured head size" was
accurate from both of my HW springers so I only use my 4.50mm sizer (4.50 mm per my digital caliper)...........
(https://i.imgur.com/7OLOLGa.jpg)(https://i.imgur.com/aIhAApF.jpg)(https://i.imgur.com/kyXgVxZ.jpg)
As a side note......... I tried to use my 4.48mm pellet sizer to sort out the supposed 4.52mm JSB Exacts and found that a HIGH percentage of the pellets dropped through the die without any sizing. I did the same with my stash of 4.52mm Air Arms domes and almost all were sized to 4.50mm! I also found that H&N FTTs had larger heads that fit snugly in my leade without sizing which is probably the reason they were accurate without "molestation" however I still sized them because it only takes about 5 seconds to size via the "homemade pellet sizer" plus each sized pellet is guaranteed to be as round as the die itself.......

I tried 7.33 Air Arms Falcons in my mild tune .177 HW95 (7.33 AA @ 900fps and CPL @ 850fps) along with 8.4 Air Arms domes and 7.9 grain die lot marked and dated boxed Crosman Premiers at 50 yards and the "light weights" where the least accurate and the boxed CPLs the most accurate. The boxed CPL (now "unobtgnium") grouped about 1/2" ctc and the 7.33AA grouped about 1 3/8"-1 1/2" ctc. LOL, still not bad for "bucket and sticks" groupings at 50 yards .........

Is 8.2 grain ok for the HW30S?
What is the maximum grain one would recommend to ensure smooth operation and longevity of the rifle?
Tom,...as long as you don't abuse your 30 with excessive dry firing,.... you can pretty much shoot whatever weight pellet you want including the barracuda's. These guns are solidly built so longevity really isn't and issue as far as that goes. But for optimal performance, accuracy, and power longevity, you would be wise to stick with any pellet in the 7 to 9 grain area. Just whatever shoots the most consistently,.....that is where you will have to try a few different pellets and see what your 30 prefers. The HW30/R7 is an awesome gun once you get it dialed in with the right pellet!! Please kept us updated on your progress. tjk

Too heavy a pellet just lessens spring life, but they can be replaced very easily. The gun itself will last more than a (human) lifetime if properly cared for.
Jim Mccari (ARH - Spring God) feels anything above 9 grains in .177 is too much even for the R1/HW80S, .... and will diminish spring longevity.
This was his comment to me a few years back ;).

Absolutely!
FWIW-There is a fellow in the classifieds, no relation just a happy customer, who will custom make a sampler pack of different pellets. 4.51 head or 4.52 head on the same pellet type. Well this guy will send you 25 pellets to find out...Just a very happy customer and the easiest, and cheapest way to find out what pellet your gun/barrel likes best. ;)

For whatever it's worth - every individual gun will vary a bit of course - my older R7 is so much smoother-shooting and more accurate with the Air Arms Falcon (a 7.3 gr roundhead made by JSB), than with any other pellet, that it's rather startling. JSB's own-label Exact 7.3 is also very good.

There were Exacts from the supposedly 4.52mm tins that had head sizes smaller than those from the 4.50mm tin and visa versa. I always found that the supposedly 4.52mm Exacts were "loose fitters" in the leade of my .177 R9 however this was driven home by a THAGC field target match a few years ago. During the match I had a "dry fire" and was annoyed at myself for neglecting to load a pellet for the shot. Well, later in the match I had ANOTHER dryfire and was very annoyed at my absentmindedness to "forget" loading a pellet the second time. As the match continued I reloaded another supposedly 4.52mm Exact but when I was relatching the barrel I SAW the JSB flip out of the leade before "latch-up". LOL...I wasn't previously forgetting to insert pellets, the "loosies" were flipping out of the leade before the actual "latch-up"!.
That fiasco prompted me to actually check the pellet head sizes of the remaining 9 tins of supposedly 4.52mm Exacts. Here are the results..........

AA Domes:
I ended up selling those tins of Exacts "fer cheap" however later I tried some 4.52mm 8.4 grain Air Arms domes and found that even though they were produced in the same JSB plant (rumor claim using Air Arms supplied dies) and found that for whatever reason the AA dome head sizes were more consistent and closer to the advertised 4.52mm...........

Measuring pellet heads really isn't an "exact science" as pertaining to the "1/100th of mm" but I've developed a "satisfactory for my purposes" method that at least gives consistent accuracy based on the actual caliper reading. I'm not very concerned with the exact "third metric place reading", just that all pellets start with a consistent head size. 1st I needed a digital caliper with pretty good resolution and testing the accuracy with a micrometer test bar..........
As a side note......... I tried to use my 4.48mm pellet sizer to sort out the supposed 4.52mm JSB Exacts and found that a HIGH percentage of the pellets dropped through the die without any sizing. I did the same with my stash of 4.52mm Air Arms domes and almost all were sized to 4.50mm! I also found that H&N FTTs had larger heads that fit snugly in my leade without sizing which is probably the reason they were accurate without "molestation" however I still sized them because it only takes about 5 seconds to size via the "homemade pellet sizer" plus each sized pellet is guaranteed to be as round as the die itself.......
Ed,
Just from the effort to seat them in the breach, I have found the JSB 8.44 in head size 4.51 to be more consistant than the ones in head size 4.52. Go figure...... ??? ::) :-\

"Just from the effort to seat them in the breach, I have found the JSB 8.44 in head size 4.51 to be more consistant than the ones in head size 4.52"
That was also my experience. The first tin of 8.4 grain JSB Exacts I bought was labeled 4.51 (typo in the previous reply stating 4.50mm) and they were indeed rather consisten but loose in my older .177 Beeman R9 leade. The next order was for 8 tins of the supposedly 4.52mm Exacts from Pyramyd Air using their "buy 4 pay for 3 deal". Well, the head sizes of those 8 "supposedly 4.52mm tins" were "all over the place".
I also found it interesting that the AA domes labeled 4.52mm I bought were actually rather consistent and "close to size" even though formed in the same Czech factory as the JSB Exacts.
