铜壳镀镍。。不容易生锈

主要是比较光滑。摩擦小, 抽壳比较可靠。防锈吗还真没见过发绿的铜壳弹

民科

言简意赅。

你们都习惯用暗语交流吗？民科啥意思？

就是说我说的不靠谱

见过，以前在枪展图便宜买的9mm，1毛多一发的铜壳回家总有几颗带着发绿的铜锈。
...

那是受潮了。

钢壳都能有效抽壳，铜壳镀镍提升不了什么。历史原因是以前牛仔们总喜欢把子弹一颗一颗放在腰带上显摆，铜 ...

我是胡说八道。还是你的对。

正解

There’s a reason that many high end defensive ammo such as the Federal Hydra Shok 9mm above have gone towards nickel plated brass:

• More corrosion resistant
• Lower coefficient of friction which allows slicker feeding in semi-autos (easier sliding rounds on top of each other in the magazine)
• Easier loading/unloading in revolvers
• Looks pretty/different which allows easier identification of brass at the range or designation of a special load
  

[size=38.9367px]好像我也没全错

[size=38.9367px]这个对上膛抽壳什么的还是有帮助的。
