Dry firing does replicate the actual thing really well imo.It costs nothing, has little effect on the rifle and will help any type of shooting.Also..I have never really understood how a longer, more balanced rifle helps much in awkward shooting positions. I do better with a carbine sized rifle everytime, a longer, heavier rifle is harder for me to stabilize and hold for a longer period of time.The effect of gravity is more of an issue as the weight is further from my body...Just me and I suppose shotgunners would say differently.Just putting it out there, folks.
