Home Forums Hunting & Shooting Hunting Optics Boone & Crockett reticle?

While at Gander last night a fellow was looking at a 4.5-14 Leu. with the B&C reticle. His question from what I understood was, when going from the different powers does the reticle stay in the same place, or is it calibrated to a certain power. I mentioned to him that with the Burris Bal.Mil-Dot they've got a mark on the power ring that indicates the calibration point, ie. 4-16 I believe is set at 14x. What do you know about this B&C reticle?

FWIW, When I shoot my 6mm with the Burris 4-16 w/BMD I use 10x and it's right on out to 300yds. That being said, I don't think going from one power to the next makes too much difference. J

There are calibration points on the power ring, they are in the form of large or small triangles depending on which cartridge you are shooting. Small is for a cadre of flat shooting bullets and large is for bigger bullets (not so flat shooting)

This is your question as I understand it: does the scope hold zero at different power settings if zerod at a particular setting? Yes, modern variable scopes are supposed to. Way back when in the early days of variable scopes I understand they had problems with that, but I have never seen it in modern scopes.

Those stadia subtension's will change value with a different magnification as the reticle is in the second focal plane. Of course the center should not (idealistically) since it's in the optical center of the scope.

As I understand your question, the point of impact will not change, how much of the target you get to see will. The lower the power the bigger the reticle area covers. Like a 1/8 targert dot on a six-20 is only covering a 1/8 of an inch at 100 yards on 20 power, it covers more than that at 200 yards. I don't have my charts before me, however on 6 power this same dot covers around an inch at a 100 yards. Hope this helps. duckgunner

Your 2nd focal plane BMD reticle will not have the same zeros for the reticle stadia other than the center x-hair axis, since the rest of the reticle stadia are not located at the optical center of the scope. Stadia subtensions change inversely with magnification changes (altho many scopes are not calibrated perfectly for magnification).

I learned this the hard way when the BMD reticle 1st came out. I attempted to zero the reticle for 200 yds. at the upper mil-dot to get more reticle compensation all the way down to the lower post tip. When i changed the magnification from 24X down to 6X and called in a coyote and attempted to shoot him at about 150 yds. with the upper dot i hit WAAAYY below him as the reticle subtensions were way off--- ALL EXCEPT FOR THE CENTER X-HAIR ZERO WHICH REMAINED THE SAME. That shot was the single reason i started learning about scopes.
