Picked up a Mossberg M72 30-30 five or so years back super cheap because it didn't cycle. It looked like it had never been cleaned inside and a thorough cleaning was all it needed. In order to deer hunt with it in Michigans Limited Zone it needs to be chambered in a straight walled cartridge at least .35" dia and with a case between 1.16" and 1.8". I was debating on rebarreling it to 445SM but think that 375 Winchester or a 1.8" version 375 M3 (MoleMan Mjollnir). Likely could use a 375 Win reamer but that would leave a long jump to the rifling, besides where's the fun in that. Using the SAAMI spec chamber drawing and a few dummy rounds a reamer print was made for a 1.8" case length. A reamer blank was turned from O1,fluted, hardened, ground and sharpened.
