I think I have my Walther Parrus shooting finally

[plumberroy]

First, I think this is too much power plant for.177
I dug out a sample of Krytox grease a salesman gave me I cleaned and blew out the spring as much as possible without disassembling it . I worked the grease down in the spring coils and put it back in the stock. I then just shot it 40-50 times ( gun has ~500 rounds on it) then I am shooting Seneca 16.1 grain pellets . With this combo,  the gun is smoothing out a shooting constistant . I have an old gamo pellet trap that will stop anything I have shot at it including 22 CB caps out of a revolver the Seneca pellets blow right through it

Roy, As you know, or should know, Krytox and Petroleum based lubricant to not play well together AT  ALL.  Do a GTA search and you will find peoples experience who do not strip and throughly clean, repeat rinse, repeat, rinse. the old grease out of their guns.  Non-clorinated brake cleaner is one of the frequent recommended cleaning agents.
You want to slow your gun down, I think the "gum balls" that are created will do just that.

If the gun was previously lubricated with Krytox, disregard the above.

I didn't think about petroleum grease  issues so thanks for the information I will watch it. I have more grease if I need to clean it up and relube I know how fast it was shooting before . I will chronograph it again in a few days. I know I can smooth it out now
Edit I did hit it with a little contact cleaner

In my experience de-petrolubifying (yeah I made the word up) a gun enough for Krytox / Ultimox takes a concerted, multi-stage degreaser job where every part of the gun's innards is repeatedly and with great detailing degreased, using at least three different degreasers where every one takes out stuff the others didn't. Even when shiny surfaces are present, the petro is still hiding in the many nooks and crannies of the piston and the chamber (bottom seam especially). Unless you do this, the "Krytoxed" gun will diesel like a mother for all eternity, rendering the super lube's properties moot.

Also, agree that the Parrus isn't really suitable for the tiny .177 caliber. It's more powerful than the 350 Mag, and even that's a really iffy proposition as a .177 cal.

Absolutely!
I do not think a little squirt of contact cleaner will be sufficient.
Plus I understand that once you use Krytox you need to scrap it off to remove it.   Or so I have been told.

You've been told wrong. I flip flop guns between Krytox and petroleum lubes all the time. It does require complete disassembly and thoroughly cleaning the parts with brake parts cleaner. You just can't mix them on different parts of spring chamber. Example lube the piston with Krytox and the spring with tar or other grease. The two will mix and make a thick sticky mess and negate the benefits of the Krytox.


Regardless of the MSDS and manufacturer specifics. Just be sure to thoroughly clean all the parts when going to or from Krytox. I used Krytox and a million petroleum lubes professionally for fifteen years at the rail road I worked for. So I have lots of experience with this stuff. Both with BB guns and trains. You're working on BB guns not space shuttles.

We will see. . I am just getting up and about I work midnights. First the spring looked like it had never been greased. It looked like it may have had graphite powder at some point. I was disappointed and should have looked at this sooner. I have worked in the automotive and medical industry for many years I didn't see enough of anything in the spring cylinder that I am concerned about contamination of the Krytox.  But if it does I will deal with it. It's not dieseling I ran 50 pellets through it just to work the Krytox in. And another 30-40 shooting for groups. If it does slow it down a little big deal ,this gun is showing 1140's across the chronograph with 7.9 grain crosman premier pellets. . I greatly appreciate everyone's input . You have given me insight on issues that may arise . Krytox won't diesel at least the grade I have is rated for Oxygen equipment. The gun was an impulse buy on clearance that I honestly wouldn't do if I had to do over again

Without beating the dead horse krytox/petroleum no-no discussion to death, Im glad that your gun is starting to come around for you. It will probably shoot even better after you do a proper rebuild.
While I have no intimate knowledge of the Walther Parris rifle, that’s a big ole pill to shoot in a .177 springer. But hey, if it works for you and your gun, I say go with it. It has always been my stance that Mag springers should be shot with magnum weight pellets. Kudos to you for that. Better to wear out a spring than needlessly fry a piston seal with lightweight pellets. Hope things continue to improve. Post pictures when you can.

Like I have said the chanel the spring rides in was dry it looked like it was lubed was a graphite powder. That Is my failure, this is the only gun I've not pulled the stock off and looked at close .  I got the Seneca pellets to try as a 4th tin free at pyramid. Light lead wadcutters get super sonic, crack like a 22lr. Crosman premier pellets are close enough to the sound barrier that they don't shoot well. The 10.4 crosman premier pellets shot okay.i had the Seneca pellets so I gave them a try. They shoot good. The few I have shot across the chronograph are doing in the 750's  the old  Gamo pellet trap I have will stop 22 CB caps out of a Ruger single six . These pellets zip right though it.  I ordered 4 more tins of the seneca pellets. By the way that gamo pellet trap is worth the money .

Roy,

If possible, try and find a .22 barrel and swap them.
Otherwise, use heavy .177 pellets.  They go up to 13 grains+.

I'm shooting 16.1 grain Seneca hunting pellets  English sparrows aren't fond of them 😎

[Lt. Dan]

My Parrus .22 is a tamed BEAST. It is a powerful powerful air rifle. Accurate as any magnum I own.

I also own a Parrus .177 that is, so far, an untamed beast. I am unable to keep any scope on it, no matter which mounts I use. I can shoot it with open sights but my eyesight won't allow that. So it sets in the back of the safe. It's way too over powered for .177.

[Robert 5mm]

The Parrus is a MAGNUM in both calibers.

I have a .177 and I used to have a .22 - both very strong shooters.

I went through a couple of scope mounts to get the scope to stay put . It literally bent the stop pin in the first mount. I think I have a UTG one piece mount that is holding at least for now . I am shooting Seneca hunting pellets that weigh 16.1 grains  the Krytox grease has seemed to smooth it out at least for now.  I have thumped a half a dozen sparrows and starlings today with it. When I bought it.177 was all that was available and they were clearance price . I know where 1 22 barrel is but after all it took me to get it shooting , I don't know if I want to change it now. I also don't think it would have the penetration in 22

[Kragman1]

 Not to pile on but I can vouch for the Parrus being "all magnum".

I have one of the clearance .177s and mine also runs over 1100 fps with 8 grain pellets.
One if these days I'd like to try some 13's in it.  Expecting 800-850 fps.  A slug sampler is worth a try too I think.  Overall, I haven't shot it enough to really break it in but it's pretty accurate, so I'm off to a good start.

I also have Robert's .22 Parrus, and it runs around 24-25 fpe for me too (basically at sea level).

Both are heavy, the synthetic .22 is heavier than the wood .177 and so far is more accurate.  The extra weight may be helping that. It loved H&N Baracuda 18s when I tried them, but it's quite accurate with most any pellet.

I needed a 1 piece BKL mount to stop the scope slippage on the .177 - nothing less worked.

I can see the .177 being limited to a specialty role of long distance shooting if I spend enough time with it to truly break it in and find the right pellets, etc.

I would love to restock the .22 in something lighter and handier, but that is a very long distance project...

[Toxylon]

I looked seriously into getting a Parrus but too late, as they were already phased out, and the remaining available-to-me stock remnants didn't have the specs I wanted (being almost all synth .177 cals).

I love the way Walther made their springers, from the safety catches on, and save for a couple of sidelever Dianas, could see myself end up with only Walthers in my spring powered active-use arsenal.

Like Brian above corroborates, the synth stock Parruses are heavier and bulkier than the wood stock ones.

[Toxylon]

I also don't think it would have the penetration in 22

I'm glad you have a gun that works so well, but I need to point out that lack of penetration is not an issue in the Parrus in .22 cal. A 350 Mag with a couple ft.lbs. under a Parrus will put a .22 cal dome straight through a 12-pound jackrabbit at 55 yards, and you are shooting sparrows and starlings.

[plumberroy]

Just an update this gun shoots better every day now. Today I put one of those 16.1 grain Seneca pellets through 2 pigeons at approximately 25 yards . I was ready to put this gun up for sale. But now I think I'll have to keep it
