I took my grandson out a couple more times, and at 100 yards and below he is within a 4 inch circle, which to me is good enough to hunt. We will only be able to practice a couple more times this summer, and he will be back to school about 350 miles away from me. While is accuracy is good, he is taking way too long to pull the trigger. He takes at least a minute to commit to pulling the trigger.
I let him lob a few at 300 yards just to see what the gun was capable of, and he never hit the target, I tried as well, and aimed at the top of the target and missed the target. That makes no difference to me, because hunting my land, his longest shot may be 60-75 yards at most. We just need to work on the the faster aiming.
