Hello,
I'm loading LC M1 Carbine brass (from CMP long ago). Does anyone have experience getting the most life out of these cases? Do they generally split at the mouth, or fail at the case head? Will annealing help? I know annealing will only help the mouth, but if that's not where they fail, it won't help.
I'm up to my 3rd load, few problems. I'm using a Dillon 550 with mostly RCBS dies, but expanding the mouth with the Dillon powder measure/funnel and taper crimping in a separate step at the 4th station.
My main question would be about case life and whether annealing will help.
Thanks.
