[QUOTE="NZ Longranger, post: 535315, member: 14"] Before the days of G7's, I used to run seriously stepped G1 BC's for my bullet of choice back then - the 7mm 180gn Berger VLD. These started at .710 out to 1000 yards and then progressively dropped until by 1700 yards I was using .4 G1. This shows how far from the G1 curve the VLD's actually are! Even with G7's I still had to step down beyond 1400 yards, but only a fraction of the G1 stepdown. So far with the Hybrids using G7, both 7mm 180's and the 338 Gen II 300's, we haven't had to step down at all out to 1400, and with the 300's to 1710 yards we also haven't needed to step down. We need to do more extended range testing with the 300's but so far to as far as we're prepared to shoot game in good conditions, the single G7 using "Shooter" is bang on. If you use G1 you'll have to use stepped BC's much beyond 1000 yards in my experience. Greg [/QUOTE]
