I think I have my Walther Parrus shooting finally

(1/4) > >>

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. ;D

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

Toxylon:
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.
