I am using a Horus Hawk with the H425 reticle. Horus' 1st-hit software, which produces come up cards for this reticle, only works with Windows XP, not Vista. I have Exbal and SiteLite software but neither allows me to specifically use the H425. Since this reticle is in SMOA (shooters minute of angle), how can I create come up cards for the H425 and how can I calculate what range each horizontal line in the reticle corresponds with? Any info would be appreciated.
