[QUOTE="SBruce, post: 437196, member: 21068"] The NF program (Exbal) doesn't accept the G7 BC's. No mater what you do or where you go, it is programed for G1. I've personally recently whitnessed (as the spotter) some discrepancies of the NF program VS actual field drops at distances between 700 and 950 yds. The same exact bullet at the same velocities you mentioned was shooting higher (quite a bit higher on some days) than the program suggested. We also noticed less wind drift than the program was calling for. The old Sierra program didn't help any either (still G1) It agreed pretty close with the Nightforce program. (Kestrel real field data (Alt by GPS, temp, BP, RH, ect) was accounted for and input into the programs). I'd been thinking that the amount of sunlight and mirage was partly to blame, and the real/true click value on the scope knobs was contributing too, but forgot about the new G7 BC's.............maybe something to that....??
