有一个担心不知道是否多余，关于.22LR

dajusha

它的底火凸出一圈，往弹匣压子弹就会想，压的时候那个凸起圈往下顶着里面的最上一发侧面，力量大了会不会引发……

centerfire压来压去也不会有压力到蛋壳底部中间，就不会担心。

这个不会的，不然都可以当摔炮玩儿了

就算你有超人的力气能把primer的地方挤憋了，它也不应该响的，我这么听说。 点22的我没见过，但我曾经有一发9毫米的Tula 钢壳弹，底火是横着装进去的，还给挤扁了跟弹底基本上平了。 我没敢打，给扔了。。。

你可以去看看CCI工厂生产.22 LR的过程，里面各种在机器里倒来倒去甩来甩去

Short answer: Current U.S. Army sensitivity requirements are 48 inch-ounces for small-rifle primers and 64 inch-ounces for large-rifle primers. (There are 192 Inch-ounces in 1 Foot-pound. In SI, 142 Inch-ounces in 1 Ft-lbs).* See below.

Maj. Gen. Julian S. Hatcher was a noted firearms expert and author of the early twentieth century. He is credited with several technical books and articles relating to military firearms. His premier works are Hatcher's Notebook and Book of the Garand, along with Pistols and Revolvers and Their Uses and Textbook of Pistols and Revolvers. In the latter work he introduced the Hatcher Scale, probably the first attempt to determine the stopping power of a handgun round by a formula. He was also a pioneer in the forensic identification of firearms and their ammunition.

Hatcher reported in 1947 that all samples of military 30-caliber (large rifle) primers must fire when a kinetic energy (KE) of 60 inch-ounces is properly delivered and none should fire with 12 inch-ounces of similar one-time impact.

*On a less technical level, Hatcher was quite creative in developing his testing methods. He specified that a metal ball weighing 4.0 ounces be dropped onto proper aligned firing pins from heights of 15 inches and 3 inches, respectively, to generate these amounts of kinetic energy for these primer tests.

下边有个答案说：

It takes about 4 pounds of force to ignite a rimfire cartridge primer.




好像随便砸一下都能达到？

但是需要准确快速的砸在边缘，几率太小。摔的话，子弹太轻，要达到那个力度，还能正巧直接撞击边缘，摔炮动作没戏

也就是说撞击方向必须从底部指向尖部么？
从侧向砸凸出缘不会引发？

你手压的力量不会高于抓壳钩吧

抓钩的加力方向是从哪边……如果从前往后是不是比较安全？

你脑补一下release bolt上膛那一下，夹手得有多疼，然后想想这一下把子弹敲进chamber都没事，为什么压子弹会有事？

说的是上膛那一下，不是抽壳

关于.22LR, 有一个好玩的玩法，就是在大子弹头上钻一个孔，把.22LR倒着推挤进去，然后...
我没有玩过，但看到我们这里有枪友玩过，应该很好玩。
