These Prvi Partizan 10mm Auto rounds are a great choice for self defense, short-range deer hunting, and back-up carry while stalking wild boar. These cartridges are constructed using non-corrosive Boxer primers fitted into reloadable brass casings which are topped by a 180 grain jacketed hollow-point (JHP) projectile. This JHP design uses an relatively narrow cavity surrounded by a high jacket with very light serrations; these features offer reliable expansion with a focus on retaining weight by preventing jacket separation. 180 grains is on the heavier side for the caliber and takes advantage 10mm's inherently high velocity to deliver greater momentum to game and threats.
