This is the documentation and the user-manual for the inner-ballistic simulation software “Gordons Reloading Tool”, in short “GRT”.
Please do read carefully, before using this software!
The Gordons Reloading Tool “GRT” is a software for handloaders and ammunition designers.
It simulates combustion characterisics, pressures and bullet speeds through ballistic
parameters and formulas.
GRT's purpose is to provide additional means to develop loads for handloaders and ammunition
designers and to avoid excessive loads, weapons disintegration/fragmentation and/or injuries.
