.22LR ballistic graph

+/- 1.7" (3.4" window) zero at 13/87 yards. Same parabolic trajectory (of course) as a .223Rem, except the range is much shorter and the window much smaller....

why did you set the zero at 85 yards? How about posting the same info for 25, 50, 75 and 100.

Thank you.

Guessing 13/85 yards because a lot don't have easy access other than a 50 ft indoor range? Name of that app please?

here's one guys...it works really well and it's free

The one the op is showing looks like the free app from Winchester.

you guys can also use the one from nikon @ nikonhunting.com

They're all the same just different formats

All rifles have 2 zeros, close and far. the object is to get the window as small as possible, ie, so that the rise above the zeros is about equal to the drop below the zeros. For my AR-15's, its a 35/300 yard zero with a 10" window. So I will setup the initial 13 yard zero until its within an inch, then make the final adjustment at 85 yards (red dot with 1 moa clicks).

I like this one........

No its not the only way to zero. You zero in accordance with your shooting.

Zeroing a .223 at 25 yards yields a duel cross zero arc of +10". You can then use the cross hairs to drive your shots out to 500 yards. Zeroing that same .223 rifle at 50 yard gains you a flat trajectory where from zero to 200 yards is the same. You loose the long range zero only, you gain a cross zero of less then your POI error.

Every trajectory is different depending on the zero. That is why I asked if he did any other calculations. This would yield results for which an educated shooter could decide which zero to use with their shooting style.

I didn't say it was the only way to zero. By the way, do you shoot 3 gun?
