==Playing With High Pressure ==
Bought a 4500 PSI, 68 cubic inch, paintball tank — carbon fiber.
Put a home built valve on it.
Pumped it up to 3600 psi (I have my own compressor).
Screwed the tank on my home built 9 MM gun (17 inch barrel).
Shot it over the crony.
Got 1000 Feet per second with a 77 grain Eun Jin pellet.
171 Foot Pounds Energy!
It was getting 150 FPE at 3200 PSI with a standard tank.
I can still go up in pressure, as long as the valve keeps opening.
Got plenty of velocity, So I can increase the projectile weight to get more power.
One of you guys (Cygnus X ) with the .457 guns might improve your FPE with this trick????

Normaly I Charge my tanks from a scuba tank, but it is only rated for 3000 PSI.
Made this adaptor to fill the tank directly from the compressor:
Damn…….now that is what I call “cooking with gas baby” 😀 the next step is to show the accuracy at that power 😯

Your Da Man! when it comes to cool builds!
Shot the pressure up to 4300 PSI.
Keep expecting something to blow up, got a little uneasy feeling.
Did a 10 shot string, 77 grain Eun Jin
No increase in velocity
Got a nice little bell curve,
965
970
990
999
995
1000
990
985
985
983
Then I shot another 12 shots on the same fill.
Last shot was 925 FPS
22 shots total

I recall when MM123522 got that compressor for a song. I was jealous then and still am.
OK, I’m just a jealous guy. 🙁
WoW is all i can say ! 😯 wish i could muck about with power but…..and do you have to brag about your home compressor !……damit…….. he dose it to wind us lot up ! 😀 LOL
HOLY MOTHER OF ALL THINGS GREAT AND SMALL….
I saw a guy do a spoof on that idea but you are the first one to make it a reality.
Awesome.
Holy Crap 😯
