As the case gets longer there are fewer & fewer bullets you can use due to bearing surface & ogive length vis a vis mag length.

Personally, I am really liking the 7.62x40. There are plenty of useful bullets for it and I easily get 2,500fps with 125gr bullets out of an AR.

In an AR I would also consider the 7.62x39, .30 American (30/6.8 SPC), .30 Remington AR and the 30 ARX/ARk/Major (all Grendel/7.62x39 variations). None of these are handicapped by having to be useful at subsonic velocities like the .300 BO.

Lots of good info on 7.62x40 bullets here - https://mdws.forumchitchat.com/


Tyrone,

Thanks for the report on your 7.62x40. I'd be interested in hearing more about your experiences with it.

You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.
