...decided to check this out, seeing as how it's a free program to download. It's pretty slick, BUT.....some of the figures I get for various bullets & powders were surprising, most of the load charges appeared as "overpressure" in the GRT, even when I duplicated Hornady & Hogdon's published data. I think my temperature (85F year round) inputs were causing the numbers I saw. I can get the program to spit out the same FPS numbers with lower charge weights. I found the "Expert" mode to give me more flexibility in what inputs I put in to match my barrel length & twist.
...BLUF, I just need to get out and test.
YMMV
