Conventional wisdom has it that .22 rifles with high velocity ammo are best sighted in at 60 or 65 yards in order to have the longest point blank range. Sometimes it's kind of fun to go back and try stuff like this for yourself, so I did it the old fashioned way, rather than break out the ballistic software.
My equipment consisted of ten yards of cord, a handful of those little orange marker flags, and a bull barreled 10/22 with a 3-9X scope. Ammo was Mini-Mag hollow points. I sighted in at 65 yards, then fired five shot groups at ten yard increments out to 100 yards. The range where I shot drops off quite a bit right in front of the bench, so the close range groups especially were shot in some pretty contorted positions, and are kind of embarrassing. The gun will do much better.
On to the pics:
Ten yards. This gun sports low rings, and the line of sight is right at 1.6" above the bore axis. I had already decided to skip the zero yard group.
Twenty yards.
Thirty, and we crossed the line of sight somewhere in the twenties.
Forty.
Fifty, and the trajectory peaked maybe an inch high somewhere in the forties.
Sixty, and they are falling back to point of aim.
Seventy, back through point of aim and still point blank.
Eighty yards, and time to start holding over.
Ninety.
One hundred, time to start wishing for a .17 HMR. That second hole from the left is two shots.
