I've noticed in the Reloading Depot loads for the 168 SMK's in 308 range up to and beyond the top end load for IMR 4895 in the new Sierra #5 manual. They list the top load as 41.3 grain of IMR 4895. I see quite a few loads well above that. My Lyman # 48 also shows max loads well above 41.3 as does my older Sierra manual. I guess my question is waht is a safe load?
