I've got RWS 8X68 brass for my 30 BooBoo that easily has over 50 firings. I never anneal. I remember a few split necks over the years but not many.
For F Class competition you'll need 600 pieces of brass for a season to be on the safe side if you shoot all matches during National. Lapua 308 palma lets say a good price of $84 per 100 so roughly $500. Giraud Annealer is roughly $500. Get 2 seasons out of a set of brass and you're breaking even. 3 or more seasons in the black!Just curious, how much brass can you buy for the price to purchase and operate an annealing machine ? How much time is spent annealing ?
Ok, I am not debating if annealing is good or bad, just trying to assess its usefulness. That being said, it appears there has not been multiple independent comprehensive studies done to deny or confirm the usefulness. Is it liken to Nitrogen in your car tires, all the Nitrogen flush machine manufacturers studies state blah, blah, blah, and thats why you need it, and you don't.I am sure every case is different. My case is: I shoot at least 5-6 thousand rounds per year. The BenchSource, when I bought it was $500.20 to my door. I have had it for about 5 years now. That is "about" 30,000 rounds during that time. I believe it has paid for itself. But how do you measure the "cost" of inconsistent brass?
Well, lapua is about 110. For 100 pieces. So I just bought 200 for 220. My annealeezz machine cost just a little more than that (275.). So even if it just gives you 5 extra fireings over brass life time, annealer is paid off quickly especially if you shoot a lot, and especially over a lifetime of shooting. It take me about 10 minutes I guess to anneal 100 and it’s automated. I start it and walk awayJust curious, how much brass can you buy for the price to purchase and operate an annealing machine ?

Riflewoman is real smartAnybody know a metallurgist? This should be a very simple answer.
I think Lapua is afraid of people doing it wrong.[/QUOTE said:This is it, right here. No control over how it’s done, so no responsibility for the final outcome, whatever it may be.
And if you haven’t seen people blame perfectly good products or components that they themselves screwed up, you’ve plainly never spent any time in the firearms industry. Sorry, but that’s the flat truth right there.
Well, not a metallurgist, but I was an aerospace engineer mechanical and know a bit about metallurgy. Worked with metallurgists and I asked one directly. See some of my posts about annealing. There’s one in this thread...http://forum.accurateshooter.com/threads/how-many-reloads-before-annealing.3963272/page-4.
I think Lapua is afraid of people doing it wrong. From what I see there’s about 90% of the information on how to “anneal” is wrong. The AMP people have data, but it is geared to their machine. But it does indicate that you must get the brass hotter than most of the recommendations out there. https://www.ampannealing.com/ Read the articles in the media tab. You might not fully understand what’s going on, but their results mirror what any metallurgist Worth his pay will tell you. None of the other machine makers do this.
And not all the information you get out of the ammo makers is good either. Norma said that brass will age harden and that is metallurgically impossible.
FWIW.
