Speer Bullets 40 S&W, 10mm Auto (400 Diameter) 180 Grain Copper Plated Flat Nose. 500 per box.
Speer swaged lead core copper plated bullets are low in cost but substantially high in accuracy. These bullets are swaged with lead wire in an effort to ensure the tightest uniformity as well as prevention of premature wearing of barrels. Use lead bullet load data when loading these bullets as well as a slight taper crimp. A maximum velocity of 1,500 fps is recommended.
These bullets feature a lead core that is completely covered by copper plating. They are resized after being plated with approximately 0.004″ of copper plating. This unique design makes them suitable for most indoor ranges, which often require the use of bullets with no exposed lead. The base is slightly concave to maximize the bullet to bore seal.
