Thread: GRT users.

When you select the cartridge you are loading for GRT will give you the max pressure - with mine when I select 223 it gives me the SAAMI maximum. With other cartridges it doesn't specify who set the max but they're both a touch over 60,000psi.

GRT doesn't have an input for primers by brand - it only differentiates between 'standard' and 'magnum'. It is part of the 'Initial pressure' function. Press the gold star on the Initial pressure line and you can input what type of primer and also bullet type - it differentiates jacketed, lead and monolithic copper from memory
