I have a 50 B&M Super Short have a lot of some brass that has been shot 20 times and counting and also know several people with them....all loads pushing 60'000 psi....it is basically like the 450 BM straight case no shoulder 1.65" long rebated rim...I've never had a problem like the 450 BM were brass gets shorter is it is fired....I think the problem is lower pressure in the 450 BM allowing the neck to get pushed forward on firing....it also could be Winchester 70 CRF on the 50 B&M SS not allowing brass to move when firing....
Have one lot 450 BM brass that have been fired 4 times at close to 60'000 psi in a bolt action only and it is still OK not getting shorter nor need to be trimmed....
