sighting in at 100 yards?

saw someone sighting in an old pump .22lr at 100 yards the other day. where would that put a standard velocity .22lr at "squirrel ranges"?

center bull at 50, 10-14"s low at 100

Just guessing, but if it's "on" at 100, standard velocity 22LR will probably be 6-7" high at 50 (which I consider to be "squirrel" range.)

The highest point would be somewhere near 75-80 yards, where it might be 9-10" high. Then dropping rapidly down to "zero" at 100, and off the charts after that.

I hunt a lot of ground squirrels with a 22LR, but I use high-velocity stuff. I like a zero at 75 yards. I'll be 2-3" high at 50 yards and only about 4" low at 100. That's about as far as I can hit a ground squirrel offhand more than 50% of the time - when it isn't windy.

ok, so then where would be the best to zero my 10/22 with a scope at? i'm talking for squirrel here.

With tiny targets like squirrels, I'd sight dead on at the exact range I expected to be shooting at. That might be 25, 45 or 75 yards depending on your terrain and cover.

Out here in the Rockies, I sight dead on at 75 yards for ground squirrels (which we do not eat). With Velocitors or WW Power Points, I'm about an inch or 1.5" high at 50 and about 3-4" low at 100. I can hold off either way for elevation. Wind is another matter!

Standard velocity ammo (to save edible meat) will have a significantly higher "arch" of trajectory. So sight in at your most common killing range, and then shoot careful groups at shorter and longer ranges to learn precisely what that kind of ammo does for you.
