Pathfinder said:at first I didnt' notice you were joking, I though you were calculating the cartridge's energy by using the action as a variable, i was confused as to how you could think that a semi-auto's action would come to play in the cartridge's ballistics. I jumped gun and for that I appologize.
Rollingrock and Foxer: no serious accusations meant, Im just poking fun.
cheers
Nope balistics for rounds are ment to be measured the proper way using a "standard" test barrel like Remington does.
Anyways no need to apologize my post was confusing I realize that now.
