发帖数: 8514 | 1 Stopping power
Back to 2000, A HPD officer told me a statistic data: on 1st hit, 9mm would
give 84% stopping; .40 &.45 would be 100% with FMJ.
On other hand, combine 9mm with Hollow Point, the stopping would be 100%
Is this true? |

9mm - This was the first semiauto pistol to be used extensively by police
agencies and replaced the 38 Special and 357 Magnum round. Early loadings of
the 147 grain round caused major stopping problems however current 147
grain designs are vastly superior. Clearly the best 9mm loads are those
driven to +P+ pressures. Of the 20 loadings evaluated, the top load was the
Federal 115 grain JHP +P+ involved in 209 shootings with 190 one shot stops
for a 91% rating. The Winchester 115 grain JHP +P+ and 127 grain Ranger SXT
+P+ both had 90% one shot stops. All five loads driven to +P+ pressures
ranked in the top 5 followed by all bullets loaded to +P pressures. Rounds
manufactured to standard pressure ratings comprised the bottom 12 loadings
in the study.
40 S&W - This caliber has become extremely popular with law enforcement
agencies due to the perceived deficiencies of the 9mm round. All
manufacturers have at least 2 loadings of this caliber and it has served
very well. The Remington 165 grain Golden Saber was used in 311 shootings
and made 292 one shot stops for a 94% rating followed closely by the CCI 165
and 155 grain loadings and the Federal 155 grain Hydra-Shok bullet. These 3
loads made 93% one shot stops. Other manufacturers loads in the 90% range
were the Federal 155 grain JHP and the CorBon 135 and 150 grain JHP bullets.
Thirteen other loadings were evaluated with the poorest being the
Winchester 180 grain FMJ that was involved in 134 encounters and made 95 (71
%) one shot stops.
45 ACP - This caliber has been around for almost 100 years and is still the
top rated round. More police agencies are using this round due to its proven
stopping ability. The large diameter, heavy bullet is the basis for the "
momentum" theory of stopping power however actual results in shootings show
a mix of "light and fast" and "slow and heavy" rounds. The Remington 185
grain Golden Saber was involved in 148 shootings and caused 142 one shot
stops for a 96% rating followed closely by the Federal 230 grain Hydra-Shok
which caused 200 one shot stops in 211 shootings for a 95% rating. Eight of
the 16 loadings examined rated above 90% one shot stops while 5 others rated
in the 80s. The poorest stoppers were the Remington, Federal and Winchester
230 grain FMJ rounds which achieved 62% one shot stops.

我只有最便宜的9mm Luger 115gr FMJ，难道我应该开始偷偷乐了吗？

发弹夹，这样我就可
以安心的用我的便宜的9mm 115 grain FMJ了。。。

发帖数: 15836 | 11 谢谢指出！但是版大的文章描述里根本没提FMJ的9mm,而只在最后的比较中提到了，所
以我猜测应该有别的数
据源。当然，这个数据到底准不准我就不知道了。不过如果是9mm FMJ写错的话，我就
一点问题也没有了：）

发帖数: 11154 | 12 老兄，俺列举了两个不同的source，意思就是说stopping power要看你相信哪种说法了
。第一个里
面的数据说明.45ACP比9mm好一些，第二个的数据说明9mm比.45ACP能量更高。两个数据
正好是反
的，看你怎么解读了。
