I looked at that. Very interesting round with a standard AR15 set up. That link led me to the 7mm raptor, and other AR loadings. Each has their plus's and minuses.I made my decision too. My next build will be................
.375 SOCOM
It'll be awhile but I'll start buying brass and dies soon. Still debating on just buying the whole upper or not. It has the ballistics and trajectory I want in a thumper caliber and still uses standard AR mags. Best part is it was created right here in Oklahoma by Tony Rumore.
After that I'll build a skinny bullet screamer.
