I must not be living right because I have had nothing but problems with S&B brass (in 45 ACP). The primer pockets act like mil surplus crimped pockets and I found the only way to avoid problems priming them in a progressive was to swage them the same way I do military (Dillon primer pocket swager). Even after that, they do not full length size without using two hands and a red face. Then, when examined, they have a ring at the base which will eventually turn into a "belted magnum" ring that really screws with feeding reliability.
I have several thousand rounds of the stuff that just sets. I'd sell it cheep but nobody would want to pay shipping.
This where I would put in the YMMV thing, but in this case it would have to mean "Your Milage 'Must' Vary".
