What Do Different Types Of Ammo Do?

There’s more to a bullet than just a ball of lead and smokeless powder.  In this article, we’re going to go over a bunch of different pistol calibers and then discuss some interesting ammunition options available in them.  There are a lot of different proprietary ammunition types (Hydro Shok, etc.) and while they are indisputably awesome – we’re going to stick the major variants.

Micro Ammunition Classes

There is obviously a lot more smaller ammunition classes but these following examples are definitely common for micro and sub-compact pistols for concealed carriers.

  • .22 LR

Small, lightweight, and extremely affordable – this is often the first ammunition a shooter will ever use.  Recoil is negligible.  This allows the shooter to acclimate to the fundamentals of firearm safety.  Is it still lethal?  Yes.  In fact, .22 LR is a preferred ammunition style for those on long range expeditions who may need to either defend themselves from animals or eat them.  So don’t let it’s small size fool you – it’s capable.

  • .25 auto

This one isn’t nearly as common as it used to be.  The .25 auto round was thought to be the perfect middle man between the .32 auto used in some European police pistols and the .22 round used for recreation.  Recoil is, again, minimal and it affords more rounds into a limited space than a .380 auto.

  • .32 auto

James Bond’s classic Post WWII Walther PPK was chambered in .32 ACP.  Perfect for British spies, old European police pistols, and concealed carriers – pistols chambered in .32 auto tend to fit easily in the palm of smaller hands.

  • .380 ACP

There has been quite some debate as to whether the .380 auto has the penetration power necessary to compete with a 9x19mm round.  It was engineered specifically to fulfill that purpose for micro and sub compact sized pistols.  The big difference between it and a 9x19mm round is 2mm in length.  So, .380 ACP could really be called 9x17mm.

    Great, but I might have left out the last para since weights were not covered. So what is the difference between 165 gr JHP + P + P and 124 gr bulk case of “what” modifier?

    I find .270 an almost perfect round for any occacian bar none. Next ‘could’ be .338 if I were called to duty as a snipe.

    You have something mixed up…the 38 spl cannot chamber 357 magnum cartridges. If you were able to do that, you would blow your gun up, and likely get seriosly injured.
    Check out my youtube videos…tagged 357 Ring Of Fire. It is a conversion to have 357 magnum performance with 158 grain bullets in a semi auto, and the magazine capacity of a 9mm.

    .357 Magnum should not be able to be loaded into a .38 …..a .38 can be loaded into a .357. Something seems to be mixed up a little on that issue.
