I do believe in Captain Crunch.
I will say in my experience GRT is not really a reliable estimate of loads until you get some velocity estimates. I have had it end up way off on some powders.sure leaning that way the more i look at this. also have Gordons Reloading Program i have been tinkering with for the loads. sure seems like that`s the way to go.
For evaluation of one powder vs another in simulation, yes it's very good. However for velocity and pressure estimates it's been less than ideal until I can input my own chronograph readings and adjust the powders Ba.
Quickload was similar, but it was consistently and reliably 10% below actual velocity estimates. GRT I never know if I'm going to be 10% below or 10% above the first time measuring velocity with a new powder. All that said, I use GRT because of the much easier user interface. And because I have GRT on my newer laptop that did not have a CD drive.
