Many try to make the popular SA cartridges more than they can be. The 6.5 Creed, 7-08 Rem, 308 WCF, all kill game way out there, usually well beyond most shooters skill levels. All three of the aforementioned get around 2,725 fps with 140, 150 and 165 grain bullets with 22” barrels. If you need 2,900 fps plus forget about adding 2” of barrel, just go to a 270 WCF, 280 Rem or a 30-06 with a 22” barrel. An over pressure load is something no one needs when hunting, it just doesn’t buy much in the real world except possible grief. This toil between velocity, barrel length, SA, LA, etc., isn’t worth losing any sleep over or worse yet something more critically needed.
