I was recently watching Dave Canterbury of Discovery channel Dual Survivor. He recommend's 12 gauge H&R as a Survival gun. He pack's chamber adapters in a back pack of the main caliber everything from .22 LR to 44 Mag. So in a bug out or survival situation he could use just about any ammo out of his shotgun. Though this concept was cool. I see he has even come out with his own line of adapter's called the Pathfinder. I will liink it seen it on slickguns.com what do you guys think about the shotgun and the adapter's. I seen some are smooth bore and some are rifled.
