It has been said that sighting high velocity .22 LR to hit dead on at 65 yards will yield the most useful point blank range. I tried it last year, with a 10/22 and a low mounted scope, right at 1.5" above the bore. Five shots each at 10, 20, etc., out to 100. Groups tended a bit to the right, as I wasn't perfectly centered up on windage at the start due to some irregular breeze while doing the initial 65 yard sight in. It was a hot day, so please ignore the sweat drips on the targets.

These go in order, from 10 to 100 yards, 10 yard intervals. Mini-Mag hollow points from an 18" barrel. The grid is on half inch centers, and the point of aim should be obvious.

In this case, it looks like conventional wisdom is pretty close to right, though the notion that sighting in dead on at 25 is a way to get this trajectory might not be just perfect. It looks like 10 yards is about 3/4" low, and both 40 and 50 yards are about 3/4" high, meaning that the peak is somewhere in between and a bit higher. Point blank range clearly doesn't extend much past 70 yards.

I am haveing a hard time too ,have always sited at 100 yards with my old targetmaster and shoot right at the shy side of 2" high at around 50yards but that is affected to some amount buy scope hieght above bore.

Good writeup. If anyone asks the effective range of a 22, this would be a good visual reference, for starters. I was going to ask how you could manage to sweat this time of year... 'til I saw these were taken last year. :)
