发帖数: 533 | 1 向各位前辈请教几个关于擦枪的问题：
1 大家擦枪用solvent戴不戴手套啊？如果戴latex或者vinyl的手套，是不是手套会被
部分溶解，在枪上留下残余？
2 枪用lubricating oil擦过以后，外表还要用布再擦一遍么？还是就让它带着一层油？
3 用了lubricating oil以后接触摩擦比较多的部位是否还需要用grease？
多谢！ |

症状
你捡来的弹壳或者从你的别的枪打过的弹壳（只要不是同一型号的），必须经过full
length resizing。如果你只有一把枪，例如你的tikka，从它打出的弹壳，你以后可以
只resize neck部分。
顺便小提示：不管你用什么材质的die来复装rifle子弹，必须lubricanting。如果不嫌
麻烦或者复杂，可以把lubricant擦去后，再装primer。 |

Hoppe‘s no.9清洁能力强，但是保护措施一般。
Break free clp清洁力不如Hoppe’s和ballistol，但是却有更好的保护效果，还带
polish cooper的效果。
我都是看别人的视频，他们做实验知道的。
有一个视频是rem oil，Hoppe‘s 9 lubricant oil，ballistol，break free CLP，
mobile 1机油和普通家用lubricant oil。用这些做实验。在金属片上喷高浓度盐水。
然后又在划分好的金属片上喷各种cleaner什么的。效果最好的是CLP，ballistol和
mobile one机油。在试验中，不用几天，只是半天，金属片就会出现锈斑。 |

共同学习。
如果你是经常使用，没必要涂什么保护油。例如Break Free CLP，里面就自带保护的成
分。CLP，顾名思义，Cleaner Lubricant Preservative。如果长时间保存，那就都擦
得干净后，然后多抹点lubricant。放在盒子里或者有专门放枪的兜子。如果，你是为
了珍藏收藏用，你可以买wax polish了。 |
