I am going to sight in a Remington Model Six 30-06 with a 3x9 Nikon scope. I only have a fifty yard range to sight in on. If I want to be zeroed at 100 or 150 yards, where should I be at fifty yards? The scope has a 40 mm objective in medium height Leupold mounts. I'll be shooting 168g. Winchester Ballistic Silvertips with a mv of 2790 with ME of 2950. Is there some table that would tell me where I should have the POA to expect the point of impact to be on at 100 yards and 150 yards ?
Thanks

My border collie is smarter than your honor student.
.226 low at 50 = zero at 100yd, 3" low at 192yd
.127 high at 50 = zero at 150yd, 3" low at 215yd
.650 high at 50 = zero at 200yd, 3" low at 249yd
1.11 high at 50 will keep you +/- 3" (6" kill zone) out to 279yd (zero = 237yd)
Now, before you make a shot (on game) past 50yd, you need to practice (and re-adjust your scope if neccessory) at the longer distances. DO NOT assume that if you sight in at 50 yards that you will actualy be zeroed at the given ranges. MV differences, bullet un-stabilization factors, scope height differences, etc will throw all these calculations right out the window.
Some guys like a mag full of lead, I still prefer one round to the head.

Realize that .127" at 50 yds for the 150 yd zero only represents 1/8th of an inch. That's gonna be a little tough to determine a group center only 1/8" above center of target. I'd settle for the 1" high (forget the .11")at 50 yds and figure it was a well sighted rifle at that range.
The first opportunity prior to hunting and in a place where I could find a 3" diameter rock or some equal thing safe to shoot at, and that was out about 150 - 200 yds, I'd see if I could bust it.
