338 Norma Magnum brass expected life

[thexman]

Just wonder for people having experience with Lapua's 338 norma magnum brass, how many firings would I expect to have if
1. I don't do hot load, would probably stay around 10-20% under maximum charge
2. Annealing after every firing

Would 10 or more firing something realistic for 33 cal magnum calibers with annealing?

Thanks

I think so. I’ve gotten 6 out of Norma brass that was still going strong before I bought new Lapua brass when it became available. I believe the Norma brass would have made it to 10, and Lapua is probably a little better than Norma, but I haven’t gotten that far yet.

I agree. 10-20 percent under max is like 40000 psi.

Kind of close 300nm Norma Brass. I shot it 8 times annealed every other firing. I cleaned it for the 9th and started to see case separation on about 20% so I chucked all 100 pieces just to be safe.
