[QUOTE="Eaglet, post: 398092, member: 3756"] In Bryan Litz Ballistic Book we find very interesting formulas. Let's use a couple of them. a 338 gr. SMK bullet out of an Edge at 2800 fps would take about [B]2.229 sec.[/B] of TOF to get to the target. using 1:10 right twist. Using the formulas: [IMG]http://i46.tinypic.com/1zch0mt.jpg[/IMG] [SIZE=3]Spin Drift alone, at 1500 yards move the bullet to the right 19.2"[/SIZE] [SIZE=3]I'm asking, please, I'm asking to how many of you this information should not be considered or taking into account? To how many of you to make it simpler and less computerized would like to ignore this info???[/SIZE] [SIZE=3]Let's say the wind is blowing and at 1500 yards is moving your bullet [B]18" left[/B] which takes very little to do that. You don't make any corrections for anything and hit the target very close enough. Then you call you shot awesome. And it is!!! you just were very lucky![/SIZE] [SIZE=3]Let's say there is absolutely no wind. For sure! No wind![/SIZE] [SIZE=3]you make no adjustments and you rifle hits the target pretty close to the center. Where most would say that rifle is right on, [B]I would know for a fact that the rifle is off!!![/B][/SIZE] [B][SIZE=3][/SIZE][/B] [/QUOTE]
