[QUOTE="Kiwi Nate, post: 362858, member: 8533"] My Sierra I6 gives 71" drift for the 140gr AB and 55.5" drift for the 180gr VLD at 1000 yards, based on the velocities you have given. A greater concern would be the lack of expansion of the core bonded AB in comparison to the softer VLD and Amax at these ranges. Speaking of the .284, I had a chance to shoot an F class .284 Win on our hunting block a couple of days ago. We (two shooters) were able to maintain a 12" group at 1260 yards through gusty winds, ranging from 7mph to 14mph, it was horrible weather with showers. It was really impressive to shoot such a nice rig in the field. The pet load for the rifle utilzed the 180gr VLD at 2950fps. I think it is a 32" tube but a 28" barrel would also come close to this. Bullet drop was predictable, right on the money but my error of wind judgement was emabarresing. The first shot was off target by a meter. Had we have been using another style of low BC bullet and I made the same poor estimation of wind drift, we would have been way further off target. I got home and immediately started googling wind meters. Thanks for posting, always interesting to look at data and talk about this kind of thing. [/QUOTE]
