I currently use G7s but it's kind of aggravating to have to put in temp, elevation, pressure, and humidity every time, even on old saved loads.
I use JBM and it has proven to be accurate with many rifles. Inputting is a pain. The computer or their program somehow leaves the inputted data in place the next time I open the program.
