[QUOTE="Pete Lincoln, post: 61740, member: 2245"] Shadow man, if your work in meters and have a scope that adjusts in .1 miliradians, you don't even need a balisticard for the alterations to range/adjustment for incline/decline. The maths is so simple and can be done in a split second. I checked out my elevation adjustments for range the hard way ( not having a computer back then) by firing for check zero at every 25m from 25m to 650m. 650 was as far away as i could get from the target. Ive since moved into the computer age and can calculate the rest to 1000m and it checks out with what i had as known data. By keeping the balistic information i need to carry with me to a minimum it means i have a far better chance of memorising it. I stick to one caliber only for my long range hunting and know it well. I can quickly work out the adjustments to my base data in my head for most situations encountered. The ACI is a god send for anyone hunting or shooting in hill country, i don't know how the hell i managed before i got mine. Pete [/QUOTE]
