I see Leupold has a new reticle available called the "Boone and Crockett" reticle. Basically the reticle provides a vertical cross hair -- broadened near the ends in typical duplex style -- with a main horizontal cross hair -- broadened near the ends in typical duplex style -- but with three additional partial horizontal cross hairs intended for 300, 400, and 500 yard zeros. The reticle is purported to be matched to cartridges which are generally matched to the .270 ballistics.

Leaving aside the argument about who is able to shoot at 400 and 500 yards (I prefer to keep my shots under 300 yards myself), what do you think about this reticle? have you seen it? Has anyone had any experience with it?

I suppose if your ballistics are close to the nominal reticle ballistics (that is, the reticle design presumes, as an example, a 0" drop at 200 yards, a 8" drop at 300 yards, a 15" drop at 400 yards, and a 35" drop at 500 yards [I don't have any idea how closely this approximates the ballistics of a .270 -- humor me for this example]) then the reticle should work for its purpose. For example, if your .338 Win Mag drops 10" at 300 yards instead of the nominal 8", you may be better using the reticle's 300 yard zero than just guesstimating with a standard reticle.

On the other hand, wouldn't the reticle have to be calibrated to the magnification the scope is set for? For example, when changing from 2.5x to 8x, the space between horizonatal cross hairs would need to change, right?

As I say, with my limited shooting skills I am wise to keep my shoots at less than 300 yards, and at this range such a reticle may be of limited value. Still, it is a gizmo or gadget which seems to offer a new and useful function.
