If I anneal how many more firings?

[Ned Ludd]

It has no effect at all on primer pockets, appreciable or otherwise. If it did the case would have been rendered unsafe.

You really enjoy nitpicking other people's statements to death, don't you? Why don't you give it a rest. Rendering cases unsafe by over-annealing IS an effect, desirable or not. Cases that are not annealed at all are more difficult to re-size, potentially leading to a change in internal volume and pressure with a given load. Moreover, cases that are not annealed also display obvious differences in seating depth force as compared to properly annealed cases, something that could also alter the pressure of a given load. Changes in pressure can have an effect on primer pockets, especially over repeated firings. The potential effect of these changes on primer pockets are likely to be small, although not zero. Nonetheless, they are potential mechanisms by which the process of annealing might affect primer pockets, and my statement was worded specifically to acknowledge that fact. It required no further clarification.

You will get more than if you don't, not sure anyone can give you a number of firing more you'll get. If you run really hot loads brass life will be shortened, if you run loads that increase pressure you will shorten brass life (split necks and primer pockets). With all that said (and there is much more) I anneal every firing as I want consistency more than anything else and extending the brass life is a plus.

Thanks I think I'll give annealing a shot this spring.

Great news, glad all the bickering did not scare you off . Try it and you may see a difference ,at least by trying it you form your opinion with actual experience...not from grumpy guys that have the mid-winter blues.

science says annealing has nothing to do with neck tension. Elasticity is the same for extra hard brass ( H04) and fully annealed (OSO50) https://www.makeitfrom.com/material-properties/UNS-C26800-CW506L-Yellow-Brass. I could toss up another dozen links to various thesis papers on metallurgy but most shooters seem to believe anecdotal evidence over scientific facts

I have over 20 firings on some cases with no annealing and no neck splits. Loose primer pockets are the cause of 100% of my case failures

My test results clearly show that the force to push a bullet into case is DRASTICALLY different annealed versus no annealed. As you know, less force is effectively a change in neck tension. This is confirmed by K&M load measurements. I will need to investigate your link.

FORUM Boss: JimSC post has been deleted. Yes annealing makes a difference. That's why all brass manufacturers do it. Read the AMP papers.

I neck size and anneal every 3rd firing. Salt bath, 950 degrees for 7-8 seconds for my Prime brass. I bump shoulder a couple thou every 5th firing or when there's a hair too much resistance when closing the bolt. If I'm going to FL size or bump shoulders, I anneal first.
