I had 2 neck separations in some 308 I was shooting out of my M1A the other day when I was trouble shooting another issue. Lapua 308 hand loader with 150 fmj. I segregated the Lapua rounds and moved on. I pulled them today and found verdigris inside almost half of them. I took one and smacked it to flatten the mouth and the neck snapped off. I proceeded to do this to the rest of them, and all of them cracked where there was green. The powder was AA2230-S (for 223 and 308). I don’t reload when the humidity is up or when it’s raining as I reload in the garage. Anyone know why it would do this? None of the powder was clumped.  “You may beat me, but you will never win.” sigmonkey-2020 “ in my opinion, anything that we can do to trigger a potential aneurysm in a leftist is a good thing and worth doing” nhtagmember 2025 | ||

The only thing I can think of is to anneal the cases. Renew the ductility of the cases. Even if it’s just the “bubba holds the case in a socket and apply the torch” cheapo method. I picked up a Burstfire annealer but haven’t put it into production yet…that will be soon! Hope you find a fix soon. -------- After the game, the King and the pawn go into the same box. | |||

+1 on annealing and brushing the inside of the necks prior to bullet seating. A bit of similar issue discussed here. ________________________________________ -- Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past me I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain. -- | |||

I do anneal. After I clean and size, next step is anneal(except pistol ammo) “You may beat me, but you will never win.” sigmonkey-2020 “ in my opinion, anything that we can do to trigger a potential aneurysm in a leftist is a good thing and worth doing” nhtagmember 2025 | |||

I misspoke, I deprime, wet clean, dry, anneal, then lube and size. On my 17 hornet I anneal after sizing because I had a buncha case crumple due to it being so thin. “You may beat me, but you will never win.” sigmonkey-2020 “ in my opinion, anything that we can do to trigger a potential aneurysm in a leftist is a good thing and worth doing” nhtagmember 2025 | |||
