A) It’s only marketing hype at close range.
B) to be fair, the 260 rem didnt sell well in ANY size.
People “fell for” the cm because it had all the attributes for longer range shooting (close chamber tolerances, easily reloadable case dimensions, standard spec in high-bc bullet weights, standard fast-twist barrel specifically to shoot heavier bullets), in a easy and cheap to shoot factory offering. I’ll take that “hype” 8 days a week. If you never shoot past 300 yards, it wasnt designed for you—so of course it seems like hype.
