I doubt it.... but I'm looking for a gauge reducer. I have no desire to shoot a 3.5 12 gauge shell in a light 12 gauge gun anyway. I have patterned 3 inch LBs out of a Beretta Xtrema 2 with a .671 hevi-shot choke, and a Stoeger M-200 with a .656 hevi-shot choke. One word - awesome. Not sure a 10, or expensive shells add anything other than weight (more to carry, and less in your wallet respectively). The little Stoeger with that combo really impressed. Both guns need optics to be effective. At 25 yards there were only a couple of pellets outside of a 4" circle. I can see guys missing. I used #5s BTW.
