Maybe I'm late to the party, but been reloading now a couple of decades. Interested to hear users experiences with GRT as an aid in load development--good, bad, accurate, etc.? There are so many holes in manufacturers data with respect to new propellants/powders and new projectiles, complicated by the lack of availability of all of the above that I find I need to create loads out of whole cloth, and I'd like to have a baseline in facts or at least a SWAG. Already installed GRT and playing with it.
