Buddy of mine has one that he keeps around his place for the critters that show up to annoy his dogs and eat his garden. I haven't shot it off the bench to test ammo types, but it will group CB Shorts around 1" at 25 yds leaning against a porch post which is about perfect for its pest elimination role. He did put a Rifle Basix trigger in it and says it is worth every penny (the trigger).
