357 Magnum – Underwood 158 Grain Bonded JHP

 Each Gold Dot® hollow point cavity is tuned by specific caliber and bullet weight to ensure optimum performance. We form the hollow point cavity in two stages. The first establishes how far the bullet can expand; the second controls the rate of expansion. This patented two-step cavity formation gives Speer engineers incredible control in the design process. Each bullet caliber and weight is tuned for optimum expansion and penetration. The bullet is then finished to provide a smooth profile for reliable feeding in semi-automatic handguns. Gold Dot was the first handgun ammunition loaded with true, bonded-core bullets. Using our exclusive Uni-Cor method, we bond the jacket to the core one molecule at a time at the very beginning of the bullet construction process. This virtually eliminates core-jacket separation
