GRT's model is a little off for 6arc.
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.
