Nosler ASP 10mm 180 Grain Jacketed Hollow Point Brass Cased Cased Pistol Ammo 20 Rounds. By adding deep skives to the nose and mouth of the copper jacket Nosler has enhanced the expansion characteristics of the ASP bullet without sacrificing the accuracy and reliable feeding that the Sporting Handgun line has been known for. The skives in the jacket mouth create precise reliefs in the jacket which allow for rapid consistent reliable expansion. This reliable expansion assures energy transfer and stopping power while limiting the likelihood of over-penetration. Equally at home on duty or in a defensive role Law Enforcement professionals and civilians alike can rest assured that the ASP bullet will perform when needed.
