hi buddy
right .22 due to the power curve most air gunners zero at between 25/27yds ,or 30yds.
i zero my .22 @ 30yds because its always the way I have done it,and if I am using a mildot scope. I am at 5yds increnctments
(sorry about spelling)
30yds is cross hairs.35yds will be 0.5 mildot,40yds will be 1.0 mildot and so on,then you got the guys who zero at 25mtrs this i am not sure of .as i work in yds, others work in mtrs.
but a well known air gunner Jim Tyler always zerod his .22 at 26/27yds with great affects.and then you are not far of your kill zone at different ranges.due to
