Need Reloading Help in Midland

Are you processing your brass before you load or during the 8 station turn? If so, how/where do you trim, chamfer and deburr?

What/who's resizing die are you using? As others have mentioned, an SB die set is near critical when processing brass that's to be used in autoloading rifles.

Are you crimping after seating the bullet? Do you have a Lyman case gauge? Dillon case gauges are WAY too generous in my opinion. Lyman is much tighter.

Processing brass before loading, size, deprime, and trim, clean then set up to load.
Lee dies.
Crimping, then checking on a Dillon case gauge.

Please let us know what you find out. I wonder if it would do better with Dillon dies.

Are you sizing them before or after you trim them, all of the 5.56 brass I have seen in the last few years has been stretched out of spec on the first firing, So even after you trim when you resize it goes back to being too long to chamber.

Both, I clean, size, deprime, swage, trim.
Then I clean, size, prime, powder, bullet drop, seat, crimp.
Maybe that could be it, but they all measure and check out identical compared to good rounds.

Dillon gauges are too large in my opinion. That may have nothing to do with your issue though. Lee dies are my least favorite. Are your dies specifically "small base" dies?

I believe they are just standard LEE .223 dies.
