I have messed around with the JBM calc, with no luck found what I am after. I am trying to get drop on my hand loaded subs I just want ballpark figures, just to get on my 12x12 steel that I shoot at. I know 50yds= about 10moa/100yds= about 17.5moa with out setting a target every 25 to 50 yds to figure it out, to save time on next outing need some help.
20in 1/10
5.1gr titegroup
150gr hornady with cannalure
running about 850 to 900fps.
And yes the 150's shoot nice out of the 1/10 twist. I didnt expect it but they do and have yielded good accuracy at 100yds.
