Anyone here build one of these yet?

Nifty little cartridge.  If you do it, I'd love to see.  Good luck.

Do you have to watch Red Dawn as a prerequisite to buying one?

It wont hurt

Was an interesting read.

It has several pluses over 300BLK, 6.8. and the 30RemAR.  Another reuse of the 223/556 cartridge.  That I like because brass would be easy to reform. Looking at the 25-45 Sharps as well.

I figured as well. After a few times reloading a .223 i can cut and reload a 277 or blackout

I wonder how it compares to the 30 American.
