A 50-5X would have been a great score to land offhand, Roger.
It's tough, no doubt about it. Best I've ever done offhand from 25 yards on an official NMLRA target was a 49-3X, and if I remember right the x's where sprinkled in. I was just wanting to reach a score of 50, but it wasn't to be.
Best I've ever reached off the sticks from 50 yards was a 50-3X, which I felt pretty good about. Then I shot a lowly 34 from 100 yards off the sticks... I think I finished 7th or 8th that day. No matter, I still got a 50 score and that was fun. I have gotten to 50 a few times from 50 yards off the sticks, but never from offhand.
