THE STOPPING POWER OF DIFFERENT HANDGUN CARTRIDGES
General Julian Hatcher, a noted forensic pathologist, in the early 1900’s developed a good formula to determine the theoretical stopping power of a firearm cartridge. His formula has withstood the test of time and validation from other studies and data related to stopping power.
You want a handgun cartridge that has a Hatcher value of over 50 for the most effective stopping power. Values over 55 have diminishing returns in that you don’t gain any significant increase in stopping power for the extra recoil and control you must cope with. Handgun cartridges that don’t make a value of at least 50, should not considered for self-defense. If the rating of your handgun cartridge is under 30, it only has about a 30% chance of producing a one shot stop. Hatcher Ratings of 30 to 49 raise a one shot stop to approximately a 50% chance. Ratings of 50 or higher produce a one shot stop about 90% of the time.
Handgun Cartridge Type ..................... Hatcher Rating
.45 ACP full metal jacket 230 grain .......... 49.1
.45 ACP jacketed hollow point 230 grain ...... 60.7
.44 Magnum full metal jacket 240 grain ....... 92.3
*.44 Magnum lead wad cutter 240 grain ......... 136.8
.44 Special full metal jacket 240 grain ...... 51.6
*.44 Special lead wad cutter 240 grain ............. 76.5
.41 Magnum full metal jacket 230 grain ............. 54
*.41 Magnum lead wad cutter 230 grain .............. 80
10 millimeter full metal jacket 180 grain .......... 50.3
10 millimeter jacketed hollow point 180 grain ..62.1
.40 S&W full metal jacket flat nose 180 grain ...... 53.4
.40 S&W jacketed hollow point 180 grain ....... 59.4
.38 Special full metal jacket 158 grain ...... 26.7
*.38 Special lead wad cutter 158 grain ............. 39.7
**.357 Magnum full metal jacket 158 grain ..... 32.7
**.357 Magnum lead wad cutter 158 grain ............ 48.5
.357 SIG full metal jacket 147 grain ................ 36.6
.357 SIG jacketed hollow point 147 grain ..... 45.2
9 millimeter full metal jacket 147 grain ............ 32.3
9 millimeter jacketed hollow point 147 grain ... 39.9
.380 Auto jacketed hollow point 95 grain ..... 18.3
.32 Auto jacketed hollow point 71 grain ...... 11.1
.25 Auto jacketed hollow point 50 grain ...... 3.7
.22 Long Rifle jacketed hollow point 40 grain ... 4.2
* Jacketed hollow points will have the same rating as wad cutter bullets if the bullet hollow tip is greater than 1/2 of the caliber of the bullet.
* .357 Magnum ratings are taken from a firearm with a 3 inch barrel. Longer barrels will raise the rating of the round. |
