I received a phone call from one of my relatives. He determined I needed a 16-gauge Winchester model 12 to add to my other model 12s. The downside is the chamber is 2 9/16". Before everyone suggests opening up the chamber to 2 3/4", the answer is a hard no. I started looking for 2 1/2" 16-gauge shells, but they seem to be pretty rare right now. My plan B is to cut down some hulls and hand load a few. To be honest, I may never shoot the thing anyway, but I don't want the old girl to starve for lack of food. Any suggestions for a light squirrel load? I've got a weird assortment of powder and I think a few wads. Thanks for any suggestions
