more .223 rem qiestions?
im loading .223 rem 50 gr hornaday z-maz(the green zombie tip). this is the first time me using this projectile. some of the ammo will not chamber in completly. im shoooting out of my ar15 and a mini 14. im using a rcbs small base die the OAL of my ammo is 2.210. my trim to lenght is 1.752-1.756. i know the manual says 1.750 but i was told 1.760 was the max. also awhile back my brother broke the de-caping pin and it seemed like he deformed the expanding ball a litlle while trying to remove to replace the pin. SO i have a feeling its 1 of 2 things ONE: the trim to length problem or TWO: maybe the expander ball is messed up and not opening the case mouth enough so when i seat and crimp it forces to much and maybe pushing the neck back more? WHAT DO YOU THINK?
