Picked up this Remington model 12 a few days ago. It has been reblued and the wood refinished, so collector value is nil, but I just wanted a model 12 to shoot. Unfortunately, I missed some issues with it and spent a few hours over three days this week trying to get it to function. I sometimes remember to just walk away for a while when I get frustrated. There was a small burr at 9 o'clock at the chamber and the inner magazine tube was sticky. Cleaned and polished those two things and still could not get reliable feeding. Turns out there was a little burr at the very end of the magazine tube where the bullet is supposed to be picked up by the lifter mechanism. Tear down number 4 or 5, and it still would not feed more than the first round. Two more brain cells kicked in and I decided to take it outside and try real ammo Vs. the aluminum snap caps I had been using to function test. That seemed to turn the trick. A quick range test yesterday and all is mostly well. No issues that were not ammo related. The front sight is so small it disappears against a black bullseye, but with colored versions I can get decent results in the 1" range at 25 yards with standard velocity ammo from an improvised rest. Much happier now and with a companion piece to the Savage 1914 I posted earlier.
