Nosler handgun bullets deliver accuracy and consistency. Each bullet is produced on fully automated machinery and Nosler polishes all Sporting Handgun bullets to a bright finish. The .45-caliber metal jacketed hollow point has exposed lead and knife-cut serrations in the jacket wall to initiate expansion. A well-defined cannelure holds jacket and core together and permits a tight crimp to eliminate bullet movement within the case. The .45-caliber Colt has a concentric, tapered jacket for maximum accuracy. A form-fitted, pure lead core for reliable expansion and maximum accuracy across a broad velocity range. Each style is .451" diameter. Per 100.
