I had a Mossberg 500... that I wish I had back. It was unreal, but I was was too inexperienced back then to know what I had as far as the pattern it produced. Heck, I thought all shotguns patterned that good. I've had a number of turkey guns since, made just for turkey, that would'nt come close to that little Mossberg 500.

It was one of the early camo models... just your regular 28" barrel with threaded chokes. I decided I wanted to hunt turkeys with it and bought a Hastings non ported extended turkey choke for about 28 bucks. I lucked into that for sure... 'cause it absolutley stomped the pattern board at 40 yards. I was shooting Winchester 3" turkey shells... High Velocity 1 3/4 oz. of #6 shot. Man, it was golden. The choke was a .665 and I'd suggest you try one in yours. Maybe it's what your gun likes too. Worth a try.
