OTC cans would definitely make 300blk more popular. If you owned one you would understand why. Super 223 vs 300 is noticeably different with 300blk being way more pleasant to shoot. Subsonic 300blk is a thing of beauty for plinking. Not exactly great for hunting

Would it displace 223. Probably not

22lr. So nice that once you go suppressed it’s hard to shoot unsuppressed with it like jack said. Hollywood quiet
