      Personal Firearms Record

    At iAmmo.com, we believe that every gun owner should keep a record of all of their firearms and other serialized items in the event of theft or loss. Similar to the FFL books that we keep here at the company, every iAmmo.com and NetBallistics employee keeps a Personal Firearm Record of all of their personal firearms or other serialized items. This practice not only helps you keep track of what guns you have in your personal possession, but it also makes reporting a lost or stolen firearm much easier should you ever find yourself in that unfortunate situation.

    Luckily, the ATF has made this process very easy for anyone to do by providing a sample Personal Firearm Record on the ATF website that can be filled in and printed. This useful document can be found at https://www.atf.gov/file/4831/download .

    Here is a screen shot of the sample document.

  • Quiet Perfection: Gemtech Subsonic .22 LR Ammo

    Quiet Perfection: Gemtech Subsonic .22 LR Ammo

    Over the past few years I have been searching for the best subsonic .22 ammunition for use with a suppressor across multiple firearm platforms. Finally, I’ve found a round that held up to all of my requirements and delivered consistent impressive performance. That round is the Gemtech Silencer Subsonic 22 LR. Manufactured by CCI in partnership with Gemtech, this ammo was specifically designed for use with suppressors. It uses clean powder, a heavier 42 grain bullet, and special lubrication on the projectile. The end result is the perfect combination of excellent and reliable performance at subsonic signatures.

    Test criteria:

    1. Subsonic signature across multiple barrel lengths
    2. Ability to cycle across numerous firearm platforms
    3. Consistent performance and reliability through multiple suppressors
    4. No baffle strikes

    Firearms used in testing:

    • Walther P22
    • Sig Sauer Mosquito
    • IWI Uzi Pistol
    • Magnum Research MLR22AT

    Suppressors used in testing:

    • Silencerco Sparrow 22
    • Gemtech Outback II


    1. Muzzle Velocity:
    One of the biggest problems with many .22 rounds marketed as “subsonic” is their performance. Remember that in order to obtain subsonic sound signatures and avoid ballistic crack, the speed of the projectile must be ratcheted back below 1,100 feet/second. This is typically accomplished by using a heavier bullet together with some powder modification, each of which can result in performance issues. If the bullet isn’t heavy enough, it can become transonic or supersonic when fired out of a longer barrel. If the bullet is too heavy, you can end up with baffle strikes or instability in flight (a problem I encountered with the 60 grain Aguila SSS Sniper SubSonic .22 ammo). If the powder mixture isn’t perfect, you can have a round that fails to fully cycle the firearm (a common problem with many subsonic .22 rounds). Luckily, Gemtech and CCI seem to have found the perfect mixture. Their 42 grain .22 LR bullet runs fairly consistent short barrel velocities of 1020 fps and is advertised to run at 1050 fps through a 24” barrel.

    2. Performance:
    Not only did the Gemtech Silencer Subsonic ammunition reliably cycle every suppressed firearm that I fed it through, but it did so with effortless consistency. There were no baffle strikes, and it delivered solid accurate hits on paper without any evidence of yawing or instability in flight.

    With excellent performance and consistent reliable cycling across numerous platforms, the Gemtech Silencer Subsonic 22 LR has proven to be the best subsonic .22 round that we have tested. If you have a suppressed .22 and are looking for the right subsonic ammo, I highly recommend this round.
