The only prob with PCPs is the limited shot count...
And thats a pain in the a$$ when yer a hours walk from
yer car & fill gear...
Well not know more...
The beginning of my 25/30fpe 100+ shot per fill PCP...
it will hold 53ci / 860cc of air in a single tank front mounted
with a 1600psi valve...
So far I have roughed up the breech valve & hammer block
The tank is 80mm in dia so there had to be a big space between
the barrel & valve placement...also room for a 32mm dia shrould.....
The bolt handle will fold into the slot under the breech when closed...
When open the bolt will completely clear the loading port....
the block is 170mm x 80mm x 25mm 6061 T6 alloy
