10mm 165gr V-crown Longshot Load with chronograph
This video demonstrates the process of testing a handloaded 10mm cartridge featuring a 165gr Sig V-Crown JHP bullet and 9.0 grains of Hodgdon Longshot powder. An experienced handloader uses a Caldwell chronograph to measure velocities and calculate muzzle energy from two different barrel lengths (3.78" Glock 29 and 5" 1911), providing objective ballistic data.
