[QUOTE="Outlaw6.0, post: 1004336, member: 23486"] So, I have to admit that I have next to zero experience running the G7 BC's. After Bryan posted his findings, I started toying with my original data running a straight up G1 of .680 @ 3100fps. I compared that with the stepped G7 straight from Bryan's chart. Pressure is Absolute Baro of 25.95 Temp 70* [B][U]1000 Yds[/U][/B] G1= 20.76 IPHY G7= 21.06 IPHY Ok just over 1/4 min difference, not bad. [B][U]1325 Yds[/U][/B] G1= 33.90 IPHY G7= 33.33 iPHY Now it's just over 1/2 min the other way around? (scratches head) I see that the stepped G7 actually increase BC as the velocity goes down. I'm just surprised to see the flip flop with the same bullet going the same speed in the same conditions. I guess the right thing to do is shoot at those distances & see which is the better choice. gun) To those of you have more experience with G7; what do you think? Maybe I should use his data to step the G1 as well..... t [/QUOTE]
