This is almost exclusively a so-called "assault rifle" round...so any future bans (however unlikely) could make supporting parts and ammo extremely scarce.300blk
: I like the versatility of this round. Supersonic, it can be quite similar to 7.62x39 (AK47) while requiring minimal alterations within the AR platform. And if you've got a forgiving bank account, it boasts tremendous supression potential. Again, primarily an "assault rifle" round, but the .223/5.56 its built around will always be a staple caliber. So a savvy reloader can find sustenance, regardless of pending legislation.308win/AR-10
: Great round, versatile round, and (unlike the above two), it's not going anywhere regardless of bans/controls/etc. 308 is a critical NATO, bolt, lever, and semiauto round that will almost
always be available at fair prices. There is very little downside to this caliber choice in my opinion.
As much as I like it, I'll probably never own a 6.8spc. I will probably add a 300blk upper shortly. And I will always own a 308win (or three). Take that for whatever it's worth.
