I have a 24" barrel winchester 1300 that I used a ssx choke tube in with the 3" magnum blends. I lasered the 40 yards and took two shots because I was on limited time. I looked around and I can't seem to find any patterns with the 3" mag blends come close to what I came up with. Is this an average pattern with the blends? Any input? I actually did worse with the heavy #7s.
