What other cartridges that fit in an AR15 provide enough of an increase in performance (increased range, dealing with wind drift better, terminal performance, etc.) over 5.56 that make them a worthy upgrade from 5.56? I know there are the duds like the .224 Valk and .22 Nosler and there are also newcomers like the 6 and 22 ARC as well as the 6.5 Grendel that has been quietly chugging along; but do any of them bring enough of an increase in performance to the table to be worth owning? Or is it just the case that if you want a meaningful performance upgrade step up to an AR10 in .308/6.5?
Thanks for reading and looking forward to your responses.
P.S. this question may have been triggered by reading about what you all are doing with your 6ARC and 6.5G rifles and having a spare lower just lying around...
