不幸言中---原来ak 74 pistol或者mosin pistol还是不要出现的好

这才明白，烟酒局原来不傻， 而且对法律许可禁的东西禁起来毫不手软。之所以7.62x54r和5.45x39军剩还能满街是，就是因为他们不是手枪弹。
这应该也是为什么SS190在5-7手枪出世后很快衣被禁了。至于ar pistol + XM855估计是北美生产商能量太大，价格又高， 所以还活着, 但是ATF也是想干掉就可以干掉。 所以， 我放弃有AK74 pistol玩的梦想啦，为了给便宜子弹留种， 还是不要有厂家造吧。

节选
Back in the 1980′s, 7.62×39 ammo was widely available in both the all-lead variety that we see today as well as the mass produced steel core variety. Since the rounds were only used in rifles, while the ammunition fit the definition of “armor piercing” as per the law, the ATF couldn’t touch it — only “armor piercing” handgun ammunition can be banned from sale. But then some damned fool designed the Draco 7.62×39 handgun, and the ATF jumped all over that like a fat kid on a bacon cheeseburger. Steel core 7.62×39 practically vanished overnight, and prices skyrocketed. Now, Black Horse Arsenal‘s new BHAKR54 might to do the same thing to 7.62x54R ammo . . .

关键是7n6和M855都不符合'armor piercing ammunition'的定义。18 US Code 921 (a) (17) (B)说得很清楚

(B) The term “armor piercing ammunition” means—
(i) a projectile or projectile core which may be used in a handgun and which is constructed entirely (excluding the presence of traces of other substances) from one or a combination of tungsten alloys, steel, iron, brass, bronze, beryllium copper, or depleted uranium; or
(ii) a full jacketed projectile larger than .22 caliber designed and intended for use in a handgun and whose jacket has a weight of more than 25 percent of the total weight of the projectile.

7n6钢芯前面有一坨铅，M855钢芯后面有一坨铅，都不是 “constructed entirely (excluding the presence of traces of other substances) from one or a combination of tungsten alloys, steel, iron, brass, bronze, beryllium copper, or depleted uranium”。5.45和5.56都小于0.22in。即使按弹头直径算两个弹头直径都大于或者等于0.22in，两个的倍加质量肯定都不到25%。所以两个'armor piercing ammunition'的定义都不符合，显然是ATF乱解释法律。感觉如果有人出钱和ATF打官司的话，应该很容易赢。不过这个不牵涉美国大弹药枪械厂的利益，会不会有官司打很难预料。我希望能有人跟他们打官司，阻止ATF的为所欲为，如果需要捐款的话我也会捐的。

下面是7n6和M855的截面图，很显然除了钢以外，弹心里还有多于'traces'量的铅。

7.62x54R的手枪那是得啥样的人才能打啊，估计就算有疯子造出来也没疯子买，除非是阿诺和史泰龙之类的。

这两种蛋的穿甲效果到底如何，肯定是不如全实心的，但肯定能穿某些甲吧，要不徒增成本谁买

毛子和中国用钢芯那是节约成本考虑，省铅。穿甲弹要用淬火的硬质钢，钨. 7n10就是穿甲弹

是的，愈加之罪，和患无词
