Hornady's published loads all show way overpressure if you enter them into GRT.
Hornady, Hodgdon, and Lyman have 6arc published data.
Berger also published some data for 105's
Id trust tested published data over a simulation model.
It might be useful to adjust GRT to match the available published data. The Hodgdon and Lyman data sets have pressure listed.
I'm curious about that myself, I have A2520, Varget and TAC to try, all modeled with the same resulting over pressure warnings.
Everything is finally done and I'm planning on making some first loads today, so I'm looking forward to the results.
I'm going to start with 24.0-26.0 TAC in .5gr increments as it is more readily available to me, and see what the chrono has to say.
