Re: Nikon BDC or MIL DOT
Nothing wrong with either really. Most ballistic programs have a MD feature that allows u to simply click a button and get your zeros. Of course this assumes accurate data inputted by the user. It's a learning process if u wanna' use it as a rangefinding tool, and maybe downrange zeroing at a power higher than the calibrated (12). I would apply the MD reticle at it's highest power, and do my own calcs for downrange zeroing from a ballistics program (at 14x the subtension between dots becomes 3.12 inch per hundred yds. instead of 3.6...according to the catalog [good idea to check the measurements at the range, although the 1 Nikon i have is exactly as advertised]). I prefer using the optic/reticle at it's highest power to get a bit more magnification, and it sort of acts as a reticle "zero stop," meaning that the subtension will obviously always be the same at the power ring's stopping point (especially important for rangefinding purposes).
That optic could also be used for windage applications mostly and twisting turrets for elevation reference.
