I have tried this before. I need software to replace TIOGA which is a DOS only solution and was not upgraded. My requirements are for the ability to PRINT out ballistics to 1500 or greater yards, for every 5 yard increment. I also need clicks to take .225 or whatever, not just the standard 1/8. 1/2, etc. I need it to take actual mounting distance from bore to center of scope and take whatever BC I need to work to MY trajectory. It would, of course, take elevation and temperature. Please read CAREFULLY and let me know if anyone meets it. If not I may never be able to leave the DOS world for this need.
