Speer Ammo 4397 Gold Dot .40 Caliber 165 Grain GDHP Reloading Bullets, 100 Count

Speer Ammo 4397 Gold Dot reloading bullets are designed for .40 caliber handloads where dependable hollow-point performance and consistent construction are important. Each 165-grain bullet uses Speer’s Gold Dot manufacturing process, which bonds the copper jacket to the lead core one molecule at a time. This bonded construction helps maintain bullet integrity during expansion while supporting nearly 100 percent weight retention, making these bullets a practical choice for personal protection ammunition development.
The 165-grain Gold Dot hollow-point design features a .400-inch bullet diameter, copper jacket material, and lead core material. The hollow-point tip is formed as part of the bullet’s overall design to promote controlled expansion, while the bonded jacket-and-core construction helps reduce the risk of jacket separation. With a listed ballistic coefficient of .138 and sectional density of .147, these bullets provide consistent specifications for reloaders working to develop reliable .40 caliber loads.
This package contains 100 Speer Gold Dot bullets for reloading applications. The bullets do not include a cannelure, so reloaders should select compatible cases, primers, powders, and loading data according to reputable reloading manuals and component guidelines. Always verify cartridge dimensions, charge weights, and completed ammunition before use, and follow all applicable safety practices. Speer Ammo part number 4397 provides a clearly identified option for reloaders seeking bonded .40 caliber hollow-point bullets with consistent weight and construction.
