Join us on the range today we are going to use GRT to analyse the following hypothesis: "Gordon's Reloading Tool (GRT), when calibrated with chronograph-derived velocity data from initial loads, accurately predicts velocity nodes (stable charge weight plateaus within ±5% velocity variation) and accuracy nodes (optimal charge weights yielding sub-MOA group sizes) for subsequent load developments in the same cartridge-bullet-powder system." Very interesting stuff. Take a look, could this help you? Your thoughts? Looks like there are powder loads that will NEVER shoot well... https://www.rexem.com.au
