GRT program calibration?

[coop2564]

Anyone know how to make a powder/velocity correction in GRT? I've worked up a load using Staball in 243 and its 200fps faster than the programs calculated velocity.
Every caliber I try to simulate with Staball is about 200 fps slower than published data. Most other powders are pretty close.

I did find a email contact in Help menu and sent email. But in help I see nothing to calibrate a powder to match your velocity. Pretty sure Quickload has a way to do that. There are some powder burn factors that can be edited, but it doesn't tell you which to use to accomplish a velocity correction. Hate to start jacking with it not knowing which one I really should tweak.

I have no advice to help, but Gordon apparently passed away a short while ago.

I had heard this. And also heard they were trying to find someone to take it over. I feel like someone will do so.
