[QUOTE="L.Sherm, post: 1511243, member: 102083"] A 6.5 140 VLD at 3220 f.p.s I'm using my 6.5x300wsm as an example has a .307 G7 b.c drifts 10" at a 9 o'clock 10m.p.h wind at 500 yds. A 6.5 .340 G7 at the same speed drifts 9" 1" difference at 500 yds. 6" at 1000. Now drop the velocity to 3150 probably what it would be with a 150-155 class bullet you have zero gain at 500 and probably a couple inches at 1000. How many hunters are good enough to make a couple inch wind call difference at 1000, I'm not. [/QUOTE]
