I have one and was having accuracy issues but it turned out that I was trying to get 100 yard accuracy out of a round that is designed for much longer ranges. The other day I took it out to about 400 against a boulder and while I did not measure the group there was just one big crater in it, about 3 inches.
Unfortunately for me, however, uncle Sam wants more of my money so I have to let it go. Might even be stupid enough to see what my local gun shop will take it my hands off it for tomorrow.
