50 yards is the flat trajectory. 1.5 miles is the range. There's quite a huge area in between you know. Kudos at getting the kid out shooting. My max range for my .22 was a 4" target at 75 yards.
I thought he was nuts to even try and it did take him some time to get the range. He can ring that plate off a rest every time. Free hand he is about 50%. The bad part is that I can't do it yet. Oh well, I guess that I'll have to stick with the scope.
I have one of those old Mossberg target rifle too, a 46b with No 4 peep site. It's one of my favorite rifles to shoot and I won't ever sell it. I bought it from a friend back in my high school days for $25
