Hi, is there a trick, or a formula to developing two different loads that would have an identical POI at a specific range?
I wish to develop Load#1, which is my hunting load, (let's pretend in .308 with a 180gr Partition and zero it at 150yds).
I'd like to have Load#2, which has the exact same POI at a training range (let's say 50 yards, using cast bullets and a light powder charge) in order to train cheaply and with very reduced noise/recoil/expense.
How?
