I inherited 2 of those 1912s, (a 12 and a 16) that look like they haven't had much use since those times. I looked up the serials and I think they were about 1915. I got some short ammo for the 16 but I never messed with the 12 as it has a drastically castoff stock that would serve for shooting with the other eye. Thanks for the tip on the Remington game loads.
