[QUOTE="Augustus, post: 591771, member: 10142"] BDCs work nice but you are limited to a certain class of firearms and weather conditions can change the trajectory causing problems at longer ranges. Using a Mil or Moa based scope eliminates this problem when used with a ballistic computer. I have used the Horus H25 a long time and I love it. I have a n easy to use formula for a 308 and an Edge or Lapua for drops and wind. I keep it in my head so it don't need batteries. 308 175 SMK 2650 Drop= Range minus 2--- example 450 yds. -2 = 2.50 mils, this will get you close from 300 to 650 yds. Wind calss are Distance times wind speed the double the result. Example, 9 mph wind 600 yds = .54 times 2 = 1.08 mils 338 Edge 300 SMK at 2850 Drop is range - 3. 800 yds -3= 5 mils Wind call is Range times wind. 800 yds 7 mph wind = .56 mils This will usually get you within a tenth of a mil or so from 300 to 600 yds for the 308 and from 400 to 1000 yds for the Edge or Lapua. For distances closer or further I have learned to tack on a tenth or two where needed. Also the Horus is deadly on targets close to a mil in height for wind calls and movers. [/QUOTE]
