been out of long range varmint hunting for about 15yrs, back then i had program to do my ballistics calculating and click value ect, it was called PCB 1.8 i liked it and it did very precise calculations, but since i got a new computer with windows 7 it does not run, is there any free software that will run on win 7 and do what PCB did.
thanks
