Does anyone here have a leupold scope with the boone and crockett retical? I just got one, seems pretty neat so far. Only thing that kinda sucks is I have to site the rifle in at 200 yards (instead of 100). Aren't many ranges around Dallas with more than 100 yards so I'm going to have to guestimate by shooting a bit high.
 
Also I can't find the "triangle" that the book talks about to select whether I have an A, B or C bullet.

What gun do you have and what bullet are you shooting?

The 21 Inch Rule applies for determining how to set your power selector. If, when sighted in at 200 yards your bullet drops 13 to 21 inches at 400 yards, set the power selector on the big triangle. If it drops more than 21 inches, up to 28 inches at 400 yards, use the smaller triangle. With this the error will be no more than 4 inches at 400 yards, 8 inches at 500. For cartridges flatter shooting than the 13 inch drop at 400 yards sight in at 300 yards and use the big triangle. The aiming points now would correspond with 300, 400, 500, 550 and 600 yards.
 
That is from the Leupold website, so you will need to know the drop of the bullet you are shooting.

get the bullet wt. velocity, and ballistic coeff. but it in a program with the program set for 100yds. it will read out the elevation for 200 yd. impact. go to range with gun --shoot target until hitting this high on target.

The 200 yard zero actually makes more sense than a 100 yard zero for a rifle that will be used in open country.  This gives you a more effective "point blank range", with less holdover required at longer distances.  It will also work just fine for most short-range big game shooting.
 
You can get pretty close to this with regular modern (nonmagnum) calibers by sighting in your rifle to shoot about 2 to 2.5 inches high at 100 yards.  You should check it at longer ranges, of course, as soon as you get a chance.  The better reloading manuals will usually give you a very good idea as to the trajectory of their bullets at different velocities and ranges.  So will some of the ammunition manufacturer's catalogs.

you dont give which range of vari you have, but as an example on 4.5x14 the large tri, is just right of the 14, and the small is just left of the 10

MrB.,
 
I have a Leupold 3.5-10X40 VXIII with the B&C reticle. When I sight in on a range with 100 yards, I use the known trajectory for my load at 100 yds and adjust the group to that height above the point of aim. That gets me on at 200 yds.
 
Look for the small and large triangle marks on the power adjustment ring, and set the appropirate triangle next to the index mark (instead of one of the power numerials).
 
I have used this scope for a couple of years now, and when I take it hunting it ensures that I will most likely get a close up shot. Karma or something.
 
jim
