It sticks. Just how much is too much?

Fairly new to sniping (about 2 wks)Just how liberal can one be with silicon oil w/o it causing problems down the line?

And what is a good grease lubricant safe for these moveable parts?

SSG with WASP piston and m180 spring. Standard hop and bucking (apologize if I am not using correct terms for describing parts).

As I was going thru configurations to see what is optimum, the head on the piston quit wanting to pop out of its cylinder. I use to have to push down (met with resistance) to try and screw the nozzle of the bolt on (part that feeds into the hopup). It'll now stay down making it ALOT easier to assemble. I sometimes have to use a bit of persuasion to remove piston if it has not been fully assembled and fired.

Just as sticking piston started happening, lost around .4J from my heavy cylinder/med brake setup.

Good airseal. 6-7 drops of silicon oil on head from initial assembly. Have cleaned and checked all components.

I want to get back in the neighborhood of 2.68J since I had obtained it prior to trying different air brakes. This happened right after I went back to my hvy/med combo to verify it was indeed the best setup .

Shot the gun this evening, 10 (X5 .43 and X5 .36) all around 2.3J and 340(.43) and 370 FPS.

I'll continue to poke around and find more info, but have not seen anything describing this scenario (yet.....)

Oils move and seep which is why I don't typically use them. As for greases, super lube, TechT, molykote 111, molykote 55, Tamiya Cera Grease, just to name a few. Basically any lube that is silicone based or PTFE based is fine.
Don't put anything in the back of the cylinder. You will have nothing but problems if you do.

For lube, use enough to wet your seals, that is it. Basically minimal. You could put a small amount on the outside of the bucking, but not necessary. Never put any on the inside of the bucking. Will wreck your accuracy and hop.

As for your power dropping, likely damaged oring or your springs are shit quality, or the springs are settling.
Oh right WASP pistons have cup seals. Still light lube around the outside surface of the cup seal.

Hmm. Have you tested the seal between the cylinder head and barrel assembly?

What bbs are you using?
Hmm I don't remember who makes valken accelerate. Though I would grab bls bbs. Heavyweight BBs (0.36g+) — Infantryshop USA

Valken is the fucking devil. I am not getting into it. Don't ask, stems from when I played paintball.

Anyway, I would also check to make sure your bucking is super clean and doesn't have any oil or grease on it. A little oil will play havoc with numbers.
You can order small quantities from mcmaster. Though would be easier to go to a bolt and screw supplier that is local to you. Not lowes or home depot. I know for a fact HD will not have anything that small. (I work for home depot, and I order all the little packs of screws and shit on the hardware aisle.)
