[QUOTE="gr8fuldoug, post: 341104, member: 9641"] OK, I just received the following from my contact at Minox: Attached are what I have for reticle images. For the BDC reticle basic drop approximations can be made for a 30 caliber center fire rifle; sighted “dead on” at 100 yards the first stadia line would be 200 yards, and the 2nd stadia line would approximate 300 yards. The up-right hash marks on the center line approximates the bullet drift for a 10 mph crosswind and the ends of the lower stadia lines approximate the effect of the same 10 mph crosswind at 200 and 300 yards. These approximates apply with the power settings of the 3-9 and 2-10 at maximum magnification, with the 3-15 it is at 10x and with the 4-20 it is at 16x. All ballistic reticles can only provide accurate drop points from test shooting the specific weapon upon which it is mounted. Even then it only is accurate for the same ammo and will vary with temperature, altitude, and barometric pressure. Most shooters understand that such reticles are a tool which needs to calibrated and not a magic wand out of the box. Personally I would probably sight a big game rifle to be dead on at 200 yards and then test shoot to determine point of impact at the additional stadia lines.
