This is the 12 bore I built from a J.P. Sauer 12g the barrels had been ruined so not much left other than work on the bore gun. I used Savage Model 210 1-35 twist rifled take off barrels the barrels were cut and silver soldered in the monobloc. The barrels measure 23.5 inches and chambered for 2 3/4 inch. I used the original ribs and re-cut the forearm hook for the new barrels it was tig welded in for strength. I made the quarter rib and it is screwed in to the rib, I put reinforced the ribs under the front sight and quarter rib as they are a little thinner than I liked for screws. Will see how they hold up. I have another rib but have not decided if it warrants using.
I also re-cut the checkering and worked out all the million dents in the wood and put a light coat of finish on.
I am working on loads now, tried the Lyman slug but did not like the results so back to the drawing board for another trial it shoots rather well just need to work up a load I like.
While looking for a set of barrels to restore the Sauer I was offered a complete shotgun with the serial number very close to the one I had, So I built the bore gun and restored the shotgun and now have a relative close matching set of 12 bore and 12g shotgun. Just need to make some accessories for them and a case. You never know what will turn up when you start looking for something. Both shotguns had been neglected for many years and I had to completely disassemble them and clean years of rust old oil and grease and crap out of the actions.
