Nah, BBS..
I'm not the suing kind. All three/year that they'll make, makes suing a kind of non-sequitur (I'm trying to impress Hoot again). The profits from three or so weapons, won't pay for the lawyers they'll need when their customers start suing them for producing such tripe. No, if 308 length cartridge is in your dreams, give me the LM and it's far Superior Performance and total reliability. Right Gunny?!?!

Witness, Gunny Here showing the way. After he loads the mag NOTICE that he bangs the mag on the table without the cartridges dumping from the mag, which happened every-time I tried such tests using 308 cases, mated to a 45cal bullets from any magazine designed for pure 308's. The LM is not only Reliable, it out performs the 458WM! Try that with the Rupture (Wink)!
The Rupture (wink), to me, is a "Buyer-Beware" preposition. Believe me, It would be fun to shoot, but in my "Minds Eye", this conversion has "ISSUES". Maybe you don't mind and maybe you really-really would mind. Pick your Poison..
