My gun is an old Rem 1100 that I had made into a turkey gun back in the late 70's(before there was such a thing as a turkey gun or turkey load)It doesn't have changable chokes and by todays standards it isn't very tight shootin.I always shot Fed 6 shot until the heavy 7's came along.Any bird I ever shot at with the 7's went down to stay.They say they hit like lead 5's but I've never been shot with either one so I really can't say.
