I have done quite a bit of reloading with 270 and 300 Win Mag. I can generally get 7 loadings out of 300 Win Mag RP brass, minimum dimension chamber. I am now primarily shooting a 6.5 284 Norma. I have Nosler brass. I am on my fourth loading, minimum dimension chamber. I am loading max load, (my gun seems to like that). I am pretty sure this will get more loads in it than a 300 Win Mag, but I doubt it will get as many loads as 22-250. Any experience anyone has will be appreciated. Side note, when I weighed all the brass, Nosler said there would be no more than a half grain variance in weight, they weren't lying. I only had one piece of brass that went more. I have 40 pieces of Norma brass, and their weights are all over the place. Thanks.
