FMJ, TMJ, CMJ有什么区别?谢谢!

"Full Metal Jacket" -
FMJ - has a true "jacket" and also an exposed lead base. During bullet formation, the copper jacket cup is loaded with lead from the back end, then the copper jacket is formed to create a small lip over the rear edge to lock the jacket around the lead center.

"Total Metal Jacket" -
CMJ/TMJ - have no exposed lead. The lead bullet is electroplated with a thin layer of copper. They are not "jacketed" as a FMJ is. Reloading data for CMJ/TMJ bullets is different than for FMJ. Usually, a load specification about half way between lead and FMJ bullets is used.

制造方法不同啦。cmt是电镀的，当然没人去特意去掉屁股上的铜层。
