Picked up one of these cute little 5 shot 3" barrel derrengers the other day. On the first outing with 22 LR cyl it seems to be keyholing at about 45'. I don't expect alot of accuracy out of this little guy but also didn't expect keyholing at that close of range.
Anyone else got experience with one of these that could give me some comparison info??

Had one with the one inch barrel back in the 80s. Neither accuracy nor reliability was its strong suit. Don't recall ever trying to shoot it for groups at 15 yards though.
