Well archery season just came out in PA. So i thought i would give turkey a try. i hunted them a little in bow season when deer weren't around. it was pretty fun. My choice is for turkey should i use a 12 g or a 20 g. my model 1897 12g patterns pretty well at about 35-40 yd. We were either shooting 4 or 6 shot lead. I think that's a good shot for turkey? We could get about 25-35 holes in a gallon of milk at that range. Its got a mod choke and cannot be changed out. Now i have a mossberg 500 in 20g. never patterned it for turkey or anything. i just use it for occasional small game. It has a full choke and can shoot up to 3" shells, the 12g can only handle 2 3/4". so what gauge do you think would be better suited, could i get away with using my 20?
