I think it's deader than a rolled-flat cat. Without some QUALITY midpriced rifles available, it's gonna die a gruesome death. I won't argue with anyone about Volquartsen quality, or Hi-Wall quality, the B-Mags have been horrible, if you bother to read rimfirecentral.
No decent quality midpriced rifles means a lot, too. Poor quality guns and spotty ammo quality means it doesn't stand much of a chance.
The idea is sweet, the practicality means it SHOULD fly well, but the applications have been nothing but a crapfest.
