I don't have a tactical scope or anything so I've been fiddling with "holdoff". The army sniper manual FM23 has some graph's and data for a long barrel M24 that is excellent - it shoot's a 7.62 also, but it's not quite the same. Do any of you mini 30 officianados have any data or any experience with holdoff? I usually zero at 200yds. How many inches above target should I have my crosshairs at 300yds and how many below at 100? Is there a trajectory chart for the 30? thanks foks.
