my theory is simply this...it takes a certain amount of recoil energy to cycle an a5, depending on the settings...less recoil energy will fail to cycle an a5...less recoil energy equates to less felt recoil...so, light loads should be identifed and then tested for felt recoil, for possible use in old double gons...if not a valid approach, then how else would one practially test the potential affect of factory loads on old gons...if not by shooting?
