i LOVE that idea!!!!!!!!!!!!! with the .22's that was a major problem for me! i would love to be able to kno where my first few shots were so i could adjust as needed....... sounds like a good idea for .22's to me. was lookin at the ballistics for my .243 wssm last night and realized it could be set up to do wat i want for f-class so i may have to get into it.... scope is my only prob.... dont have the money for somethin to see that far at the moment
