First, and most crucial: I know how to plug the OPRV, so after that, how many times can I pump before it explodes? Heh...
Second, I intend on making a 1' long brass breech nested in pvc. Is this too long/too short? Does the barrel length matter? I do know a looser dart fit is ideal.
Any other advice/recommendations would be very much appreciated.
p.s. I intend on using just the internals for a panther front-barrel attachment for my strayven. So I don't care about having to chop up the shell or anything like that.
