Good article from a good guy that knows his business.
I'm not a fan of the CM but everything he states in the article is absolutely true and I've been a 6.5 fan since long before he CM was even envisioned.
If you are just starting out and want a 6.5 it's a good choice because of all the factory and aftermarket support but I'm not going to be selling any of my other 6.5's to buy one or replacing any of them when it's time for a barrel change with one.
Every shooter, every hunter, every cartridge and every bullet has it's limitations. Never exceed any of those limitations on game, save that for target shooting.
