Speer Gold Dot Personal Protection Features The Speer Gold Dot bullet uses Speer s signature bonding process fusing the jacket to the lead core one atom at a time so the two never separate on impact. This bonding technology produces nearly 100 percent weight retention along with reliable uniform expansion both critical traits in a defensive handload. A higher-volume hollow point cavity is engineered specifically to aid expansion at the lower velocities common to short-barreled handguns where many conventional hollow points fail to open reliably. The .357 inch diameter and 135 grain weight are matched to standard .38 Special dimensions for dependable feeding and function. Because Gold Dot bullets virtually eliminate core and jacket separation they also produce a highly uniform jacket that contributes to tighter accuracy compared to less consistent designs. Reliable feeding in semi-automatic pistols is engineered into the bullet s profile as well extending its usefulness beyond revolver handloads. This 100-count package is intended strictly as a reloading component for handloaders assembling their own .38 Special defensive ammunition not as finished ready-to-fire cartridges. For reloaders who trust Gold Dot s terminal performance and want to build their own short-barrel defensive loads this bullet delivers proven law-enforcement-grade design.
