[QUOTE="Mysticplayer, post: 80693, member: 8947"] Let's see if recent experience agrees with yours. Using JBM ballistic software too and hornady bullets. With their listed BC or just mucking about, not even close. All scope adjustments retested and verified on a measured surface so I know that part is right. Solution...which G function are you using? G1? If so, the data the program spits out is completely wrong. With a 162gr Amax, I had to use the G7 profile and got within 2 clicks out to 650yds. Close enough for me. So the BC debate can continue to rage. A 0.65 G7 BC is way higher then a G1 0.65 BC. I now just enter what I field data then change the G function until I get something that is close. If three points are close, the rest of the data will also work out. Honestly, don't care which G function I end up with. I just want a drop table that works for my load. Jerry [/QUOTE]
