i have been using quickload for about a dozen years.
i like it.
if your shooting results vary from thier predictions, you can play with data to adjust the perfomace to match what you got and then use the adjustment in the future.
you can add bullets.
you can add cases..as in specific to a rifle
the only issue is you lose all this when you get a software update...unless they fixed that.
not cheap but very good
