The results of experimental detonation velocity for milled double-base gunpowder are presented in this paper. The gunpowder was milled in a mill with wet process. Three different granulations of milled gunpowder were then used for formation of charges with different diameters, which were detonated using a booster made of plastic explosive. Detonation velocities were measured using Explomet-FO~® apparatus. Obtained results were then analyzed using a non-linear regression models.
