Comparison of common carry caliber ballistics


Questions about carry ammo comes up all the time with people's hearsay, instead of compilation of actual data, so here is any easy reference postOriginal 10mm FBI Load for Reference point2. Original 10mm FBI Load for Reference pointFor Reference so people can see where modern 9mm is at The Original FBI 10mm 180 gr. Federal Load w Seirra JHP (not the later 190 gr. for use in longer barreled MP5/10s) from FBI DATA fired from a3.75" barrel 922 fps 18.33" .536 had a 95% success rate in their testing at 340 ft. lbs. of ME.5" barrel 931 fps 17.24 .547 95% success rate in their testing 346.4 ft. lbs......Compare that to my two top selections in 9mm below and you will see we are doing well in modern times Muzzle Energy Comparison of different Pistol/Revolver Calibers9mm 3.5" barrel 350-450 ft. lbs. of Muzzle Energy (350 being higher end of standard pressure to 377 for +p to 425-450 ft. lbs for Plus P Plus) Muzzle Energy Comparison of the Best Rounds from common carry sized barrels in 3 common Calibers.357 2" barrel 425 ft. lbs (recoil and follow up shot speed?).38+p 2" barrel 213 ft. lbs. from Plus P.380 2.8" barrel 125-128 ft. lbs.40 3.42" barrel 344-438 ft. lbs.45 3.64" barrel 414-426 ft. lbs from mostly Plus P, 1 Standard.410 S&W Governor 347 ft. lbs The Governor has a 2.75" Chamber PLUS 2.75" Barrel .45 Colt S&W Governor 321-379 ft. lbs.References on Ballistics From multiple sources comparing them. What the FBI has actually issued in various calibers since Miami shootout, everyone quotes 12-18 but doesn't look at what they have issued in 10mm,.40, and 9mm...sure seems FBI likes 16.5" or more a lot better than 13.5" pretty bullets others seem to.Luckygunner, ShootingTheBull, Tnoutdoors9, and others ballistic tests.Alternate Look at Handgun stopping power-Street DataHandgun Ammunition Stopping Power Update-Street Data Written by Evan MarshallFBI and NYPD dataDr. Gary Roberts“Handgun Wounding Factors and Effectiveness” by Urey Patrick of the FBI FTUQuotes from Massad AyoobThe best 3-4 9mm choices are just as good if not better than the best 3-4 .45 and .40 choices with all the benefits that 9mm provides. I personally like 16.5-18.5" Penetration based on what the FBI has actually approved for carry in 10mm, .40, and 9mm since the Miami Shootout.This is 4 Layer Denim Tests from LuckyGunner9mm 124 gr HST 1135 fps 18'3" .61 355 ft. lbs. of muzzle energy9mm 124 gr Plus P Golden Saber 1170 fps 18.2" .66 377 ft. lbs. ME.40 S&W - 155 Grain HST JHP 1079 fps 16'8" .68 401 ft. lbs. ME.40 S&W - 180 gr HST JHP 960 fps 18'4" .72 368 ft. lbs. ME.45 ACP +P - 185 gr JHP - Golden Saber 1018 fps 15.7" .76 426 ft. lbs. of energy.45 ACP +P 200 Grain XTP JHP -Hornady C 965 fps 18" .59 414 ft. lbs. ME.45 ACP +P - 230 gr JHP - Ranger 905 fps 14.4" 1.00" 418 ft. lbs. ME ( I want to point out, in real world where a bad guy may only have a single cotton T-shirt covering his frontal center mass, this round may be dangerously on the shallow end of penetration depths fyi.).357 2" 357 Mag - 140 gr XPB HP - Barnes VOR-TX 1169 fps 17.1" .66 425 ft. lbs (recoil, & follow up times?)In .38 2" barrel K6 from lucky gunner data the best IMO Remington 125 gr Golden Saber +P 877 fps 13.7" avg .62 This round also ranked tied for second place in Evan Marshalls Street Data....So that backs Gel tests up. (May want to Dutch Load Rounds #2 and #4 w/ Hornady 125 gr XTP American Gunner for greater penetration.380 2.8" barrel pocket pistol best IMO opinion from ShootingtheBull because of great penetration is the Fiocchi 90 gr. XTP app 790 fps 13.41" .412 in BARE GEL 4 Layer Denim app 800 fps 15.69" .394 avg. diameter.... Penetration is good, BUT ONLY 125-128 ft. lbs. Muzzle Energy.For .45 holdouts, there is still this From Massad Ayoob "A famous wound ballistics specialist whose work was pivotal to the FBI’s testing protocols was Dr. Martin Fackler, who died last month. In a 2012 interview Dr. Fackler said, “The size of the hole the bullet makes, the .45 is bigger than a nine-mill. But how much bigger, by diameter, it really doesn’t give you the measure of how much tissue it disrupts. What does is the area of a circle. Area of a circle, it was pi-r-squared. It’s the radius squared. So, if you take your .45, your point four-five-one and your nine-millimeter as your point three-five-five, take half, take the radius, square that, and what you’ll find is that the volume, or the area, of damaged tissue made by the .45 is about sixty percent more than made by the nine.” via /r/CCW http://ift.tt/2A2Egut
