Hammerli Pneuma Elite 10

[darryl]

Home depot have Duct Seal.  It's in the electrical department where the small fuses and small connectors are.  don't look in the high power electrical department.  it's in the same isle as the light bulbs and small switches.  I found them at the same isle in 10 Home Depot.  also best to call to see how much do they have in stock.

Lowes have them also, but cost $2.50 per stick, instead of $2 at home depot.  I bought like 120 of these to make 4 duct seal of 14" x 14"

thanks Eddie. I'll go back and check.

Stefan, excellent work.
coax, show me the way, man!

Yesterday shooting, I wasn't happy. Pellets were all over the place, for my taste. My AT loved JSB 18.1 before cleaning the bore with JB paste.
Especially with a regulated air cylinder. Last night, I found that it is loosing air. That was fixed with replacing the o ring that goes between the valve and cylinder body (24x2,5mm).
Today, I found out that my barrel now loves JSB Jumbo RS pellets. Regulator was at 125 BAR before, I put it on 130 now (saw a post that some fella has it on 150 bar and +4 turns CCW, and gets 40 regdd shots from 200 BAR).
This is what I got. And I'm stacking pellets at 30 and 50 meters, and on 100 meters, groups vary from 3-5 cm.

[coax]

Stefan, your gun will probably still like the 18.1s after it gets some lead in the barrel after the cleaning.  I have found the same thing after cleaning with JB, but the accuracy usually come back after 20-50 shots.  I even put at least 5 pellets of the type that I want group thru the rifle to season the barrel, before measuring groups when switching between different pellets.

[Stefan]

I shot over 500 pellets through it since cleaning, and only JSB Jumbo RS now works good.

[coax]

That's odd.  I wouldn't be too happy about that since I bought mine to shoot the heavy pellets with.

[darryl]

Stephan, I want to say if your rifle loves those pellets keep feeding them to it. Another option is to buy a replacement barrel, and go easy on the JB paste. I may replace the barrel on mine before it's all over.
You can always try a pellet with a larger head diameter. Good luck.

[darryl]

Darryl, Bob is right about the sear and hammer. Also about a piece of dirt floating around. I would suggest checking it out. Prolly allot cheaper than new barrel. And with your erratic fps you will never shoot straight.. Barrels don't cause fps problems like you discribe.

I've discovered some tiny brass particles  inside the body today. Also some wear on the brass hammer-movement bushing where it seems to be rubbing against the hammer sear. I assume that's the cause of the small brass particles. Will adjusting the trigger help this? I disassembled and checked the air valve. It's clean with no dirt or signs of wear. 

[coax]

Think those are the particles causing the velocity shifts?  Let's hope so.  You mean if your turn it into a shooter then you'll sell it, after all the work?

[darryl]

If I get it sorted out I'm likely to sell it now. I've found a new love and I hope to afford one someday. The Pneuma would be sacrificed on the alter of the next thing. I won't sell a problem child though (four magazines, plus a Neil Clague LDC )

RWS Rapier?  Daystate Gran Prix Mk4 FT?

[darryl]

Rapier or it's FX counterpart the Timberwolf. Not as powerful as the Pneuma, and certainly different with a two-shot capacity. I prefer the stock on the Rapier version. In reality these rifles come up for sale about as often as Haley's Comet shows up. I'd be keeping the Pneuma for a long time. At least I have access to parts. Maybe a Lothar Walther barrel one day. That barrel's an option on some Hatsan PCPs, iirc.   

[coax]

I am looking forward to Hatsan coming to the US with more models, but the prices need to be reasonable for the amount of sophistication in the design.  I hope this pneuma works out as my high power .22.  I'm keeping the fingers crossed.  I eventually want a .22 hammer and one down closer to 20fpe with a good shot count.  We'll see.  I 've already saved the money for the Hammerli AR20 FT, if they ever get it here in 12ft/lb or higher version.  If that Hammerli never becomes reality in the near future, I may spring for a FX (or even a Marauder, but I'm not fond of the stock or the scattered reports shotty accuracy).

[darryl]

At one time i really had an interest in the Hatsan 155 Torpedo, a springer. Now, the BT65 looks interesting. I've read that Hatsan is constantly improving it's product line. So I'm still hopeful. I hope your Pneuma works out too. Mine as well. Hatsan is a respected name everywhere it's sold.

As for the Marauder, there are many stories about the .22 barrels having QC problems. Some say Crosman is not changing the tooling soon enough to keep tighter tolerances. I can say this. I bought a Marauder rifle barrel and put it on my P-rod (after a bit of fiddling around to fit it), and seems very accurate. Unfortunately I only have one picture of a group, and I do have a video of the P-rod where the sound with a full shroud is captured  (not to hijack the thread) Pneuma! Pneuma!! Pneuma!!

[coax]

We'll get the Pneumas squared away before you know it.  I always have wind here and it keeps snowing, so not sure when I'll get to group test at 50yds again.  I did put down three praire dogs today though, out to 70yds on the neighbors property and targets have improved to that range also.  However, the "Truth" will come from group testing.

[darryl]

seems to me the truth is in the pudding (that you turned those prairie dogs into)!! 70 yards! 

[coax]

But, the only headshot was one at about 25yds.  He seemed to be standing there laughing at me.  I didn't have the confidence to go for headshots on the ones that were at 60 and 70yds in the wind, so went for the neck and hit in chest area.  Praire dogs will make it back to their holes on adrenaline with anything short of a head, neck, or upper spine shot.

[darryl]

Heck coax, WITH MY PNEUMA AS IT IS, I'd do better by throwing rocks at those little critters! Your rifle very good imo. I'm still waiting on parts. Then I'll give it another go. Keep up the good work (and let me know if you find the secret fix).

[coax]

The rifle is not good at this point.  It needs to average an inch and preferably 1/2 to 3/4, then I'll call it good.  You can then shoot with confidence knowing if you do your part it will be there.  I've seen airguns shoot like a laser at 20-30 yds. and fall on their face at 50-55yds.  This Pneuma was the same way.  At 50 and beyond is where you see what they are made of. 

How long till you get your parts? How much were the major parts?

[darryl]

coax, I forgot to ask about the price of the barrel, but I got an email out to Anna Dalton of UMAREX tonight, asking about the price. Of course I'll pass that on to you when I get it (hopefully tomorrow). The hammer,adjustment screw, and TP o-ring plus the cleat? I forget how much the cost is, but I'd say less than $20.00 shipped. The prices seemed reasonable, but I didn't write them down. I was told the parts would ship today. Ought to be here by Thursday.

From the groups Stefan is getting with his AT44, I have to agree with you about what we should expect for grouping out to 50 yards. Oh, I never heard back from HatsanUSA about the LW barrel. But I kow Jim Gaska gets some LW barrels in from time to time in a group buy, and turns them to fit. $100.00, I think.

[rsterne]

Original Hatsan LW barrels are $160 in Canada.... Our Hatsans are a good price here, so the factory Hatsan LW barrels may not be that much different in the USA (once they become available).... Are you guys aware that the AT44 is available in two different lengths?.... The longer one has a 230 cc air reservoir and a 3.4" longer barrel.... LW barrels are a factory option ($100 extra, installed, IIRC if ordered with the gun) in either length....
