[QUOTE="73driver, post: 2243117, member: 36473"] In the study the only copper jacketed lead bullet to start a fire was a Nosler Partition. Standard cup and core lead bullets are not much of a fire danger. The shock of the metal going from 3000-2500 fps to a complete stop when impacting a rock or steel plate turns a solid into super heated molten slag. The reason that copper solids are the worst is because the ductile nature of copper and its higher melting point. When copper transitions from a solid to molten slag it first has a higher temperature than the lead and the copper solids throw of bigger chunks of heated slag. The cup and core lead bullets splatter into smaller pieces and the pieces of a shattered lead bullet are smaller and cooler than a copper solid. The small pieces of the copper jacket that splatter off a cup and core bullet impact are so small they cool off faster than the copper clumps that come off a solid or a partition. Also keep in mind that the tougher thicker copper jackets on some bullets are not what I would consider a standard cup and core bullet. I would expect a premium thicker copper jacketed bullet to be an equal fire danger as a Partition. [/QUOTE]
