RE: .7mm Mag. Ammo
I've used Federal in a lot of applications and had good results. I'm not sure if the Federal Barnes TSX is the same bullet as the Barnes X-Bullet.
I've used PMC in some of my handguns for practice without jam or misfire.
I thought I would give the PMC/Barnes a shot and see how they perform.
Itwon't hurt to checkthem out anyway.
