NOS Brass and when to anneal.

[bozo699]

Why not? You could anneal it with an amp 10 times and it wouldn't get any softer.

Or any other annealer if it was done correctly.

The 20 test pieces were annealed and 6 split to various degrees..

That depends - if you buy decent brass, like Lapua, it is annealed from factory - ready for first load/firing.

All brands are annealed at the factory. A double anneal doesn't hurt anything.

Your spot on Webster!… all brass has been annealed usually several time at the munitions plant, if they didn’t it would split out during the drawing process but when people don’t see the discolored neck shoulder like Lapua brass looks they think it hasn’t been annealed at the factory.

But do you anneal new brass before loading the first time ?

I dont, AMP says after the first firing, then each time after firing again. new brass was probably annealed when it was made.

Another update..... The Norma brass had NO issues. I tested both annealed and non annealed. Seating pressure was much stiffer with the non annealed though. End result is Remington will be scrapped and ALL the Norma will be annealed.

Too bad about the crap brass.
I have 20 virgin boxes of Norma 6MM Rem from the late '70's. I will be annealing them before shooting.

I have a bunch of Herters (Norma) 6mm brass from the early 70s that will also get annealed before loading .
