[QUOTE="Broz, post: 816647, member: 7503"] Yes, there is a windage correction for CD too. It is dependent on Latitude and azmuth. I think your SD is not working due to lack of entered info in your bullet data. You can choose one or the other, none or both. SD alone should be .5 to .75 moa at 1000. My 300 win with a 210 shows 1.0 moa at 1500 for SD alone. Coriolis will either add or subtract horizontal drift to SD when both are on. For example at 1500 with coriolis on and shooting 280* azmuth I get 1.4 moa and 1 moa of it is SD. To get your spin drift to work, and I will assume CD as well, you will need to have all and proper bullet data entered. That means bullet Dia.,weight, and Length too. If you do not have bullet length entered that could be your problem. Hold on the bullet file, select edit and fill in the blanks then save. Jeff [/QUOTE]
