Don't get me wrong, I love how the straighter walled cartridge allows for use in an AR magazine instead of needing to go full-on banana, but ballistically it just seems to me like a 7.62 x 39... only a lot more expensive.

I do love that they're giving users other options of course, the only way to make 300 blackout less expensive and more prevalent is of course to make more firearms in the caliber so the demand goes up.
