My M1A is just fine as my .308 example, and my AR 6.5 Grendel is good out to 1000+ yards, so I'm happy with what I have. Thought about a Creedmoor, but felt the Grendel was close enough.Are there "better" cartridges... sure.
I am quite happy with my .308 and 6.5CM AR's. ... are they the best thing 'ever ? Nah... but they sure do what I want out of them.
Emary came back with a cartridge that checked all the boxes and was prepared to name it the 6.5 Demille. Dennis and Dennis being the humble guy that he is suggested it be named for his employer; Creedmoor Sports. And the rest is history.Ironically the article misses one of the main reasons the 260 and 6.5CM were created for... to fit into a Large Frame AR and the magazines used by them. ( As well as smaller actions then the typical 30/06 size. )
Pick up them 29palms brass. 🤣Also, if you are just starting in precision shooting or are recoil sensitive then 6.5C might be worth switching to. I was already heavy into .308 Win with many rifles so it wasn't worth it to me. I have dope for my FN SPR to 1210 yards and have a Kestrel if I need some help calculating wind drift at long range so of course I'm sticking with .308Win/7.62x51.
