what can i use besides a shrader valve for high pressure because my shrader valve stars to get extruded , hahaha, at 370 PSI, are there any treaded shared valves somewhere

ya i just have runs as administrator and no problem in ggdt

in GGDT is the projectile mass in grain or grams, wtf is gm, grain is gr, and gram is g, so wich one is it

where should i put a spring???

this is my first gun wtf, Look at QUAKEBUSH rifle, damn strong air gun, if you have the right steel you can make one better, and kill game at 200 yards, not to mention 50 yards


Edit by MrCrowley.

anybody know the PSI rating for galvanized pipe and fittings, safe working pressure??????? what about brass is it weaker or stronger

this is what i wanna do for high pressure pump, 2 stage

I plan on transforming it in an hunting rifle, or totally replacing it with steel components and take it to 1000 PSI, or more with a home made HP pump. i...
