THIS. Use a ballistics app (I like Lapua Ballistics) and it will tell you how many clicks it is for any distance from the distance that you zero in on. It will put you on paper and likely even close to the bull when changing distances.
What method do you generally use?
A. Right-size with bushing and done
B. Under-size with bushing then expand with mandrel
C. Something other than A. or B.
Thank you!
