I do a lot of rabbit hunting with my Remington Sportsman 58, which has a Modified barrel. It does not have a changable choke tube. This gun works GREAT for rabbit. My question though, is will it be suffecient for turkey hunting? I am going for the 1st time in a month. I was looking at maybe picking up a Mossy 835 w/a full choke. I would rather not spend an extra $300 if I dont have to, but would the one I have be OK? Or would I be better off with a full choke?
