As I recall, A-Square had the 6.5/308 and somehow Big Green rammed their named 260 thru the SAAMI, now about the A-Square vs. CM, it's been beat to death. Owned several of each, factory and custom. Bottom line, all get the job done. Want MORE performance than a CM, well most handload the A-Square....so if you want more than a MOOR, go SWEDE, use a Tikka action or rifle, or just go LA. If you need more than a CM, why not just go 270, easy peasy.........but better yet a 280 has better twist.......but why mess with that when you can just grab a 7RM, which is even MORE than any CM...280, or 270. Ok...I am done. CM or Swede are hard to beat. For the record, at this time - a 47 in a 20" and a CM in 24 T3X.......learn your clicks and they will do fine. On the 260, BRASS choice is a BIG factor in accuracy, Rem is CRAP. Use FC 308 or 7/08 and get tight groups, Lapua is top grade, and Nosler...at least the early production will perform. H4350, kiss lands.........enjoy.
