2.6 inches at 100 yards will give you a MPBR of about 291 yards with that ammunition based on their claim of 2990 fps, and the BC of .391. It appears that is the 117 grain interlock spire point boat tail bullet. The zero will be at about 247 yards. Two inches at 100 will not get you to 300. But you would be good at 200.
With a 100 grain bullet you can easily get to 3300 fps. That's all I use for deer. Shoots a little flatter than the 117.

rcollier asked:
I am happy with my last three shot group at 100 yds I am about 4" highshooting factory load 117gr Hornaday Whitetail ammo. Do I want to bring it down another 2" to zero at 200 yds?

Thanks for the info on MPBR, I dont think I am that sophisticated yet.
I think I am going to sight in for 2" high at 100yds and go from there.
rc,
Still not sure I understand - Are you going to shoot 200 yds and verify the zero?

My understanding was to be 2" high at 100 would be center at 200 yds.
rc,
If you want a 200 yd zero - Shoot it and zero at 200 yds,
then return to 100yds and see how high it really is.

Snyper, if you can not quickly and accurately determine distance, you might want to repeat "snyper" training.
If you are going to shoot at 200 yards, then you can't go wrong with the 200 yard zero. If your question is in relation to the trajectory arc at 100 yards for a 200 yard zero because you don't have a 200 yard range to zero the rifle, then you need about +1.5 inches (1.48) at 100 yards for a 200 yard zero with that cartridge.
That is the easy way. If you would wish to be good out to a certain range without worrying about Kentucky windage and elevation, that is why folks use the MPBR zero. A deer has about a 9 inch diameter vital zone, so if you are aiming in the center of it, you still have a 3 inch margin of error up, down, right, or left.
If you zero for 200, and try shoot at a deer a 300, and try to guess on the hold over you will then have the "pitiful hit" or a miss that Reynolds referred to. This could result in a animal with a leg blown off that you will likely never find.
But, if you want a 200 yard zero, shoot the rifle at 200, or +1.5 at 100 will be very close to that.
