Specs
2" piston valve
3" x 36" chamber
2" x 60" barrel (i know the CB ratios is off, i plan on making a new barrel eventually)
3/4" ball valve for pilot (i am currently waiting for a sprinkler valve to pilot)
I still have to make a barrel support, get the sprinkler valve, and paint.





i threw this in as a way to bring up suggestions to get to 200 psi (my compressor, though big, only gets to 150 psi)

EDIT:
Got it out yesterday and did some damage, though mostly spuds, so i didn't end up completely tearing my targets to shreds. I decided to go with a sanding drum as a piston, it works great, but it seems to have cut down on efficiency to some extent, though its much more reliable and seals every time...
This is the only video i have, sorry for the poor quality... This is a shot to a piece of 3/16 stainless steel sheet with a wood plug.

The hole in the middle is the damage from the shot (the plug then continued to tear the second layer from the first, of this scrap piece of industrial appliance), the face of it is caved in from a few potatoes.

dents to a stop sign that we have... it was in our yard when we moved in

potato hitting a piece of 1/2 in plywood

I don't remember what holes belong to what ammunition and what guns... (3/4 in plywood)
