I'm not saying you are wrong, but... anyone can order a custom bbl. from a bbl mfg., and have a reamer made to what ever specs they like.I'm not sure what you are asking. I know the creator of this caliber pretty well. and he has said more than once that when the barrels that people have ordered directly through him and another online source there will be 49 barrels that have been made and sold.
Wow! Into page 6 and never saw my one and only.
7.62x40WT. .223 or 5.56 brass cut down to 40mm with a 110-150 gr. .308 bullet. Bill Wilson of Wilson Combat did a lot of load developement and sells the dies, barrels, and brass on his store's website. Very similar to 300 Blackout, but smaller bullets going way faster. Deadly on pigs and deer. AR platform, only changes from a typical AR build is barrel and magazines. Uses standard bcg.
I'd be very interested in hearing about your experience with this..30 Remington
7.7 Arisaka
7.65x53 Mauser
soon: .40 Super (which is a necked-down .45 Win Mag)
