I just got a Mossberg 500 Turkey model 12 gauge. It came with the factory XX-Full turkey choke. I know you're supposed to try a bunch of load/choke combinations but it's just not financially possible right now. Has anyone had any experience with a 500 and Winchester shells in general? I bought 2 boxes of the Winchester DoubleX, 3", 1125 fps, 2 oz. of #5 shot. Has anyone had experience with the DoubleX loads. Any advice you could give would be greatly appreciated, thanks!
