I picked up a couple of 18" 16 twist threaded barrels for a Savage on 6br for my brother and myself just for heavy bullet subsonic loads with a can and screwed one on a Savage 10 action that was a 308 with a blind magazine and it feeds just fine with the factory FTX, I haven't tried it with the with the big blunt cast bullets yet maybe this weekend, yours may feed as a BDL
