6.5 Grendel - 140gr Hornady Match BTHP with N540
This video details the process of reloading 6.5 Grendel ammunition using 140-grain Hornady Match BTHP bullets and Vihtavuori N540 powder. The instructor outlines a load development strategy, starting with 25.5 grains and increasing in 0.5-grain increments up to 27.5 grains, while meticulously setting overall cartridge length and monitoring for pressure signs. The testing also explores the impact of a suppressor on point of impact and group size, linking it to an upcoming video on barrel harmonics.
