If one was to build a PCP/HPA gun in .177
how much pressure would be reqired to toss a
10g pellet @ 1000fps though a 18" , 450mm
barrel...useing a boss valve...?
Why a .177..because I an't got a .177 PCP...
Was thinking of converting a 22xx
but there is two meany constaints in
trying to convert a exsiting design..
So I intend to build from scratch..
The main constraint in useing a 22xx is how
the air entrers the barrel...the air goes into
the barrel at 90* to the direction the pellet travels...
easy to build but just dosn't seem cleaver to me..
""I know most do it that way"
And the 22xx valve / hammer are the wrong way around for
what I want to acheaive... I require the hammer at the front,
muzzel end....
I have two designs/ideas...feed the air though centre
of the bolt...but you still have to load the pellet into
a silly little chamber...OR use a swing up breech that
the pellet is loaded into and the pellet is fired directly
from the breech into the barrel...Which is what Evanix
do in there AR6..but they use a mag not a swing up breech..
And yer know how much kick those things have..
just wonder how meany times I'm going to have to build some
componets to get it right...a few times I venture...
better order extra alloy..
and it would be a bullpup...
SO how much pressure do I need behined the pellet..?
I thinking a 3000psi tank requlated to 1400psi to shift
the pellet...?????? and would like a BIG shot count as
well / possable...
