Finally took my Charter Arms Pathfinder .22 to the range to sight it in after replacing the front sight blade like 6 years ago. The odd thing was that the first cylinder full all hit the target sideways. Straight lines instead of round holes in the target. Decent enough group size (for my eyesight anyways). This was at 10 yards. The following 5 cylinders all shot normally. Round holes and decent enough accuracy. What happened?
