I've sorta sidelined the small rifle primer brass just because I've accumulated so much Hornady brass from guys who don't reload.

It's easier to use one recipe at a time. For small rifle primer, I'd avoid the Wolf SRMs because they're too mild, but AR Match and BR-4s are plenty hot enough to fire reliably.
