In my shadow maybe, but my loads are um…light…i mainly shoot idpa carry optics and my load needs to make power factor (125) and the last time they were chronograph’d one of my 3 failed (I think my crimp was off)
In steel challenge there is no power factor (and I don’t shoot uspsa, where there is a power factor)
In my czechmate, with that huge a$$ 4 port comp, my hand loads wouldn’t function the slide even if I had a 5 pound recoil spring, the manual that comes with it, they say you have to shoot 9mm major to make it function (feed the comp!) but I’ve read way too many bad things about 9 major to shoot it, hard on springs, hard on the gun, you can only safely reload 1 or 2 kinds of brass and that you can only use that brass once!
