With Alpha Munitions 7mm SWC brass, the choice is pretty easy.
If there’s a cartridge I load for and Alpha makes brass for it, I will just buy that and not look back.
I’ve loaded for 7mm-08 in the past, and really love that cartridge. It’s what 7.62x51 should have been, and we should have known that from 7x57 Mauser performance already. 7x57 Mauser was one of the best military rifle cartridges ever developed and mass-produced.
Instead, we stubbornly stuck with the .30 cal bore because of institutional biases in Army Ordnance Board/CONARC. I don’t hate .30 cal, but you just get better performance from 7mm with higher sectional density for weight.
.276 Pedersen was our missed opportunity, which would have solidified 7mm in the US arsenal system going into the 1950s after the War. Would have made an awesome little AR-10 with a smaller frame, higher mag capacity, using the Pedersen’s case head.
