I used to shoot cowbiy fast draw, uses 45 long colt cartrige, a wax plug propelled with just a primer. (The cartrige us specially made for this). Ove never seen or heard of something like that in an auto. The wax gums up the barrel pretty fast so ckeaning is fairly constant.
I was just wondering if anyone has ever used/made wax bullets for practice? I know they're primarily used in revolvers, since they aren't strong enough to cycle a semi-auto, but was wondering if anyone had ever tried them with a semi-auto?
I know nothing of this but have to wonder how a wax bullet would hold up to hitting a feed ramp?
Not wax, but Speer makes a plastic bullet that you push into one of their plastic cases. It also only uses a primer.
I use them in a revolver in the basement for practice. They wouldn't cycle an auto.
