Shot 410 slug through aH&R shotgun shotgun with a aim point on it. Set the rig up for my kid as a50 yard deer gun when we didn't have anything else. 6 inch group at 50 yards free handed. Never got to shoot at deer with it but it did ok on paper and was cheap to put together because I didn't have to buy anything I didn't already have and recoil wasn't to much for the little ones.
