You will need a .308 Magazine. 6.5 Creedmoor will work out of both our polymer and steel magazines meant for 308 Winchester as they are very similar in case dimensions. In fact, a lot of calibers similar in size to the 308 will work without issue.
-22-250 Remington ** Due to the extreme taper on the casing, magazines work best at a reduced capacity of 3 - 6 rounds.
Extremely helpful article. I've been filtering for 6.5 creedmoor mags and only getting .308 mags listed. Now I know why. Thanks for letting us know!
Awesome Phil, glad the article was able to help!
