It’s likely some of us were shooting things with ARs before dla was born, but he could just be a late bloomer.....or never even bud out.

Just about every chambering in an AR that I know of fills some specific niche.....whether your’s or not, there’s a fit for it. I don’t stretch AR15s much for hunting, as I feel they’re compromised after 300, vs other hunting options. Doesn’t mean they won’t work.....they just aren’t as well suited for it as an AR10-sized semi or any other gun taking not-AR15 cartridge offerings. .....but sometimes it’s about seeing where you can go with a platform, and more power to them.
