It can be adjusted from light to heavy. I prefer a taper crimp over it, but then a consistent case length will be more critical. I trim em every time for .223, despite the fact that you can get away with doing it every second or third firing. I don't keep track any more, so I just trim every time. I DO check cases for signs of impending case head separation. If numerous cases in a lot start showing the tell tale signs, I scrap the lot.Does that Factory Crimp put more stress on neck mouth? From the pictures I looked at it looks like a serious crimp.
Agreed, but I still like to crimp my blasting/plinking/SHTF ammo.Proper neck tension will require 40-50+ pounds of force to move a bullet in a case.
That amount of impact from a poor feeding rifle or magazine will bend a bullet nose sideways before it slips.
That said, and I know you agree with this, NO amount of crimp will make up for poor neck tension...Period.
