Crimped Primer Removal
Quote from Reloader on February 11, 2017, 1:35 amIs the Dillon universal depriming die suitable to remove crimped primers from 5.56 cases? I have read posts on this forum of priming bolts and stems becoming bent and I wonder if the force required to remove the crimped primers is part of the cause. Whad do you feel is the most appropriate way to remove crimped primers?

Normally, I decap everything with a Lee but the pin bent then broke so, foolishly, I threw more money at that ten cent piece of brass and broke my Dillon .223 resizing die's decapping pin.
When I replaced the tip and there was extreme runout observed while screwing the die into the die head, I removed the "Complete Decap Assembly" and chucked-up the threaded part in the lathe. I observed .050" TIR and was amazed at what extremely light taps were required to bend the butter soft "Upper Decap Bolt" back into shape. I was certainly *not impressed* by this.

Quote from Reloader on April 23, 2021, 2:00 amWhen I decided to use my trim die to resize my .223 brass, I stopped using the Dillon .223 resize die emtirely. I switched to a Lee 45 acp resize die for all of my rifle decapping. Although I continue to be a devotee of Dillon dies, the Lee decapping rod assembly is particularly durable.
And YES! I fully understand the frustration of bending or breaking expensive tools to process a piece of brass.Terry
