In 1986, a tragic Miami shootout<\/a> between eight out-gunned FBI agents and a pair of bank-robbers led to the death of two agents. The aftermath impacted not only the type of firearms and response methods used by law enforcement, but led to the development of a more powerful and effective round: the .40 Smith & Wesson.<\/p>\n

.40 S&W ammunition<\/a>\u00a0has become one of the most popular rounds for target-shooting, hunting, and personal defense. Made specifically for semi-automatic handguns, the round is fast, powerful, and more effective in the field, giving law enforcement a greater chance at protecting themselves and citizens. If you use the 40 cal pistol for personal protection, you need to find the best 40 S&W ammo for self-defense to carry with you.<\/p>\n

Our Picks for Best 40 S&W Self-Defense Ammo<\/h2>\n

If you have to choose one load as the best 40 S&W ammo for self-defense, we would recommend the largest-expanding round that is within the FBI\u2019s penetration range.<\/p>\n

1.) You can typically find Federal’s 40 S&W 180 grain HST ammo in-stock<\/a> at a reasonable price. This is our top pick for shooters.<\/strong><\/p>\n

2.)<\/strong> According to our exhaustive testing, this would also make the Winchester Ranger Talon with 180-grain hollow points<\/a> a great choice. This had the best shot diameter (0.74 inches) for all rounds in the desired penetration range, and was in the top five in the other two categories. (16.46 inches penetration, 1,118 feet per second)<\/p>\n

We recommend any .40 S&W round with over 0.6 inches of expansion and 12 to 18 inches of penetration as a reliable load for your personal-protection handgun. This means that there are may .40 S&W rounds that will work for concealed carry and home defense. Speer’s Gold Dot<\/a> is another solid choice.<\/p>\n\n

Performance Standards from the FBI: Our Guide for the \u201cBest\u201d<\/h4>\n

Using ballistics testing, we can determine the best ammo for penetration, expansion,\u00a0and velocity.<\/figcaption><\/figure>\n

There are many opinions about what stats should be the primary concern for self-defense ammunition. Is velocity or muzzle energy more important? Is shot mushrooming the primary concern or should gun owners be focused on shot penetration? For issues such as these, it\u2019s best to look at authoritative sources, such as the FBI, which extends a lot of effort researching and developing the most effective firearms. According to their standards, penetration for a self-defense round should be between 12 and 18 inches. Anything below 12 inches will not provide enough stopping power, while anything over 18 inches gives the chance for over-penetration. (More on over-penetration below.)<\/p>\n

Methodology: How To Determine the Best 40 S&W Ammo for Self-Defense<\/strong><\/h3>\n

To create this list, we looked at ballistic-gel results recorded as part of our massive self-defense ammo testing project<\/a>. Using numbers from this testing as our guide, we were able to determine the best rounds for penetration, expansion (shot diameter), and velocity. We then considered all three in conjunction to give you our recommendation for the best 40 S&W ammunition for self-defense or concealed carry.<\/p>\n

Five Best 40 S&W Ammo Loads for Penetration<\/h3>\n

Of all the statistics you can research on self-defense ammunition, few are as important as penetration. When a shot has deep penetration, it will be able to reach vital organs and create enough rapid blood loss to stop a threat as quickly as possible. The FBI\u2019s standards require that a bullet be capable of penetrating at least 12 inches in ballistic gel testing; anything less and the bullet will not have the reliable penetration required to stop a threat. However, over-penetration remains an issue as well.<\/p>\n

Over-penetration occurs when a bullet travels through a target or barrier. It’s a concern for all carriers of self-defense handguns. Over-penetration can cause injury, damage, and even death by creating unintended damage downrange. For this reason, the FBI standard\u2019s state that a bullet should not penetrate over 18 inches during ballistics-gel testing. To make our list, we looked at the deepest penetration among the tested .40 S&W rounds that do not go over 18 inches. The Ammo To Go testing showed that seven tested rounds had penetration over 18 inches, with one going over 23 inches. The deepest-penetrating rounds without going over 18 inches were:<\/p>\n

    \n
  1. Speer Gold Dot, 165-grain HP: 17.24 inches<\/li>\n
  2. Winchester Supreme Elite, 180-grain Bonded PDX 17.02 inches<\/li>\n
  3. Federal Hydra-Shok 165-grain HP: 16.7 inches<\/li>\n
  4. Winchester Ranger Talon, 180-grain HP: 16.46 inches<\/li>\n
  5. Winchester Supreme Elite, 165-grain Bonded PDX: 16.44 inches<\/li>\n<\/ol>\n

    Five Best .40 S&W Rounds for Shot Diameter<\/h3>\n
    \"a

    Shot diameter is another crucial factor in ammunition for personal protection. When it comes to shot diameter, the larger the better, as bigger expansion will create a larger wound channel and give the bullet a greater chance at stopping the threat. Shot diameter is driven by the speed and energy of the bullet; the faster a bullet is traveling, the more it will expand, generally speaking. However, bullet design and energy can also create faster or larger expansions.<\/p>\n

    When an expanding round strikes the target, it mushrooms into a larger diameter, doing greater damage to the target. How much should a bullet expand? There are no official standards, but the firearms community in general holds that a bullet should expand 1.5-times its original diameter or larger. For a .40 S&W cartridge, which hold a 0.4-inch-diameter bullet, the expansion should be at least 0.6 inches. (0.4 x 1.5 = 0.6) Unlike penetration, there is no maximum number for shot diameter.<\/p>\n

    To make our list of the top .40 S&W rounds for shot diameter, we looked at the largest expansion but eliminated rounds that do not fall within the FBI\u2019s penetration-standards of 12 to 18 inches. The largest shot diameter for .40 S&W rounds within the FBI\u2019s penetration range:<\/p>\n

      \n
    1. Winchester Ranger Talon, 180-grain HP: .74 inches<\/a><\/li>\n
    2. Winchester Ranger Talon, 165-grain HP: .73 inches<\/a><\/li>\n
    3. Federal Premium HST, 180-grain HP: .72 inches<\/a><\/li>\n
    4. Winchester Supreme Elite, 165-grain Bonded PDX: .71 inches<\/a><\/li>\n
    5. Federal Premium Tactical HST, 180-grain JHP: .69 inches<\/a><\/li>\n<\/ol>\n\n

      Five Best .40 S&W Rounds for Average Velocity<\/h3>\n

      Finally, velocity is an important part of the list. Velocity can impact how a bullet performs at the target, but can also have an effect on the overall accuracy of the bullet. Terminal ballistics are dependent on high-quality velocity, which is why the .40 S&W, which is one of the faster handgun cartridges, remains so popular. In general, the faster a bullet is traveling, the more penetration you will have from your personal defense ammunition. A faster bullet will also have more energy and drive faster expansion, giving you greater stopping power when you need it most. Once again, we looked at the fastest rounds but eliminated those outside of the FBI\u2019s penetration standards. The fastest velocity for .40 S&W rounds within the FBI\u2019s penetration range:<\/p>\n

        \n
      1. Magtech First Defense Justice, 130-grain SCHP: 1,233 feet per second<\/li>\n
      2. Winchester Silver Tip 155-grain HP: 1,214<\/li>\n
      3. Speer Gold Dot LE, 155-grain GDHP: 1,143 feet per second<\/li>\n
      4. Winchester Ranger Talon, 165-grain HP: 1,127 feet per second<\/li>\n
      5. Winchester Ranger Talon, 180-grain HP: 1,118 feet per second<\/li>\n<\/ol>\n

        Conclusion<\/h3>\n

        There are a number of good choices for self-defense out there in 40 S&W. The round was born to neutralize threats and while its popularity has waned since the early 2000’s, it’s still a wonderful caliber for defensive situations. We hope our testing and this guide offers you some peace of mind if you’re ever in a situation to rely upon your ammo in a life-and-death situation.<\/p>\n","protected":false},"excerpt":{"rendered":"
