[QUOTE="sierra22, post: 64833, member: 949"] I use a free program called PCB 1.8. It's available on the net and will give both metric or imperial (correct name??) units. It works reasonably well at the shorter ranges (600minus) as long as I juggle Bc to something that corresponds ok to what the bullet really flies. It might be helpful to know that a loss off 1hPa or 0.02953"Hg corresponds to about 27m or 30m (cannot remember which right know) increase in altitude under standard atmosphere conditions.. (app 88 or 98.5ft) MOA and MIL... well, it's an aquired taste which way you'll swing I guess. As long as you have a metric scope (1cm@100m) everything is dividable by 10. ¨ What will 56clicks translate to in holdover? 5,6 MIL. Good, simple math for a tired head... [/QUOTE]
