9mm Crimp

[RT]

How much are you crimping 9mm bullets? I haven`t been crimping much, bullets tight but cant see any crimp.

I usually just take the bell out of the case.

9mm brass are designed to be tapered. Taking out the bell out the case mouth when seating the projectile should be good enough. Crimping is not necessary, unless you are loading really long OAL for 9mm major, which could expose a lot of the projectile and may need crimping the case mouth in order to hold the projectile in place for cycling/battery.
