    124 grain 9mm Luger Full Metal Jacketed Round Nose (FMJ RN) at a velocity of 1305 ft/s (398 m/s) 158 grain .357 Magnum Jacketed Soft Point (JSP) at a velocity of 1430 ft/s (436 m/s). This is roughly equivalent to the obsolete NIJ Level II ballistic protection level. [10] NIJ HG2 9mm Luger.44 Magnum: This armor would protect against:

  3. 9mm Major - Wikipedia

    en.wikipedia.org/wiki/9mm_Major

    9mm Major is a wildcat cartridge of the 9mm Luger specifically for competition pistols designed to handle very high pressure. It is used in practical shooting competitions like International Practical Shooting Confederation (IPSC) and United States Practical Shooting Association (USPSA) to achieve a "Major" power factor, which earns more points for hits in specific zones on paper targets ...

    Specifically, I commonly shoot both guns, 357 mag and 10 mm, with light 38 special or light 40 S&W equivalent loads up to full power 357 magnum or full power 10 mm loads in a wide range of bullet weights. If anyone believes this to be non-neutral, please explain the concept to me. Gflory 14:17, 10 December 2010 (UTC)

    en.wikipedia.org/wiki/Power_factor_(shooting_sports)

    Conversion from kilo grain feet per second to newton-seconds is trivial, since both the grain and foot is based on SI units. One troy grain is defined as 0.064 798 91 grams exactly [ 1 ] and one international foot is defined as 0.3048 meters , giving the exact conversion factor of 0.019 750 707 768 .

    en.wikipedia.org/wiki/.400_Cor-bon

    Handloaders have worked up safe loads using 180 gr (12 g) bullets at 1,250 ft/s (380 m/s) making it an adequate round for hunting some medium game at close distances. [ 13 ] For practical shooting competitors, the .400 Corbon makes IPSC Major Power Factor of 175 and surpasses the IDPA Enhanced Service Pistol's Power Floor of 125,000 in most ...

    en.wikipedia.org/wiki/10mm_Auto

    A 180 grain hollow point bullet was "acquired and handloaded to a velocity of 950 feet per second". Later on, factory-loaded ammunition was acquired that met their requirements. During the trials, the 10mm was found to be comparable to the .45 ACP (Not surprising as the weights and velocities were so similar), but the 10mm was found to take up ...

    en.wikipedia.org/wiki/.38_Special

    In the case of target loads, a 148 gr (9.6 g) bullet is propelled to only 690 ft/s (210 m/s). [25] The closest comparisons are the 380 ACP , which fires much lighter bullets slightly faster than most .38 Special loads; the 9×19mm Parabellum , which fires a somewhat lighter bullet significantly faster; and the .38 Super , which fires a ...
