need some help zeroing a .221
I'm using factory 50 grain ammo.

a ballistic chart shows the following:

velocity
2800
2137
1580
1180
0 through 300 yards

trajectory
0
-7
-28
100 through 300 yards

what is a good 100 yard zero?

and, I have to sight the rifle at 50 yards due to space and time limitations- how do I get the 100 yard zero at 50 yards? In other words, how high at 50 do I zero to get the 100 yard zero?

thanks.

Here's a ballistic calculator that you can use to do all your own figgeren.
