FMJ and LRN down the same barrel

[DaFadda]

I promise.... I won't mention the use of mercury in doing an absolutely perfect job of cleaning out lead from a barrel. I won't say a word about how mercury amalgamates (bonds) with lead and causes it to dissipate in just a few minutes.

This not said... Mercury is a dangerous element, and can cause health concerns if not handled properly. Since most people would not know how to handle it properly, I will not suggest its use to clear lead from a barrel, even if it was in common use as little as 30 years ago.

Just "not" sayin'

Based on your Santa post, I'm pretty sure why your FCD die is not working right.

If you are forming brass from 223, and not reaming or turning the necks, then your necks are way too thick, preventing them from going into the collet. You are essentially turning the FCD die into a conventional crimp die, as which it would work very poorly if at all.

Try some factory 300 BLK brass, I'll bet you get a completely different result.

To crimp the thick necks you might be able to spread the fingers of the collet a little.

Had some success and some failures on Sunday, I am still busy cleaning guns and haven't had time to write up how it went. As soon as I can I will update.

I see what you mean about the Lee Crimp die and will also check that out with factory and cut brass.
