Overexposure to lead vapor can cause serious health problems, but 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. This is not loaded ammunition.
Note: Rainier recommends a maximum velocity of 1,500 fps.
