[QUOTE="SBruce, post: 865480, member: 21068"] Shooting the 140 Hunting VLD in my 6.5-284. I purposely canted my scope so when I dial 22 minutes my poi is off to the left of Top Dead Center by ~ 3/4" at 100 yds. Since doing that, I haven't noticed any excessive spin drift at LR. Everything seems to dial in fine out to 1000 yds anyway. I believe we're shooting the same bullet. Just for record, I didn't do this because of problems, did it to counteract normal spin drift and coriolis effects. I had heard that it's normal to get 9-12" of right drift @ 1000 yds depending on the bullet and the rifling twist and coriolis is supposed to be another 3" ?? [/QUOTE]
