I just don’t have a need for bigger than 6.8 or something like 300 HAMR or 7.62x39 in an AR15. If I did, the 357 AR Max would be a ‘want’, over the 350 ‘Almost’. I guess if I had bears or such and hunted them with an AR, one of the 473 case head cartridges might fill some niche. I just don’t see it, but good on ya if it’s your thing. I have no problem jumping to 308-based guns/cartridges, when they’re really what’s warranted.
