Re: iSnipe and Ballistic calculators
You might email him again, and add a suggestion. A really good ballistic program will have a provision for having actual clicks which are different from the nominal value.
For example, Leupold scopes with M1 knobs nominally adjust in quarter MOA clicks - however the scope clicks are actually closer to 1 inch per hundred yards.
To be really useful, a ballistic program needs to have the ability to handle that, so a user can measure his <span style="font-style: italic">actual</span> click value, and put it into the program. That way the program can calculate what he really has to dial to achieve the required point of impact change. There are programs which do that.
