Loading Lee 356-95-RF, soft lead, powder coated, .357". CCI once-fired brass.
Size/flare/seat with Lee .380 3-die set.
OAL: 0.950"
Seating and crimping with Lee bullet seater die. The tightest crimp I've been able to get measures 0.368" at the outside of the case mouth. Bullets are loose and will pull out of most cases. They will not go any deeper in when pushed by hand. I've adjusted the bullet seater die up and down, and can't get the crimp any tighter.
I use Lee dies in several other calibers and have been able to crimp much more than needed. Would a Lee factory crimp die solve this issue?
