I need to read up on the .300 HAMR. I own and shoot the Blackout, but this one is new to me.

For Ar shooters, it's boils down to having something fairly close to .308 Winchester without having to go up to an AR-10 platform. That's what excites me.

And it would keep me from having to get an AR-10 -- just another barrel for the 15. I like it.

If you like to shoot your blackout supersonic, then the ham'r is for you. It's basically a blackout with with a little more case capacity. Ballistically it reminds me of the 300 savage.

I actually have two Blackout uppers, one with subsonic twist and one with supersonic, so I could just get a HAMR barrel to replace the supersonic Blackout barrel. You're saving me money on an AR-10 and I can redirect those funds to handguns. It's a great day to be alive.

That gun sounds absolutely insane. I mean "insane" as in "a person that starts fights with decorative trees". Wish I could try that pistol out. Have fun at the competition.

That tree had it coming!

I always love your posts, Matthew, something new to learn in each. It also resonates with a book I just bought that explains how self-imposed limits makes for greater creativity. 🫡

I absolutely agree with that. Much of my best writing has been done with strict criteria, and some of my favourite guns are the ones I built using only materials I had available.
