Other than the program by shooter ready is there another simulator out there? Im looking for one where I could add my own ballistic info for caliber and bullet selections.

I know its not a replacement for practice, just looking for something to pass the time and using repetition to enhance memory of formulas and range estimation.

Hunt hard, kill clean, waste nothing and offer no apologies.
