[QUOTE="RockyMtnMT, post: 1631516, member: 7999"] This thread really blew up, so someone may have already said this. Seems like there is a bit of confusion with zero range and sight in range and carrying the rifle with the scope set at MPBR. Whatever range a person prefers to validate the load and set the turrets to the zero mark when the bullet impact is dead center the bullseye. Whether that be 100, 200, our 300 etc. This is the zero. Then using a ballistics calculator that will calculate the MPBR zero, you then dial up the elevation turret to that point. Technically you are now walking around with your rifle dialed up from the actual zero. So if your MPBR zero is 325y you then dial your scope up whatever that value is, 2.25 moa we'll say just for example. Now we know based on our ballistics that set for MPBR zero we are good to, well say 420y, and hold dead center and still land inside the pre determined 5" radius. Now if the shot comes about that is 642y we then go to our ballistics and determine that we need a total dial up from the actual zero of, we'll say 5.75 moa. We have already dialed up to 2.25 moa and that is what is showing on the elevation turret, we now just continue to dial up to 5.75 moa for the 642y shot. When done you dial back down to 2.25 moa and you ate back to MPBR zero. You can always dial back to the physical zero and nothing changes with your ballistics program. [/QUOTE]
