Suppressing without the suppressor

CCI Quiet 22, a new round that that measures 68db at the ears so you can safely shoot without hearing protection. I wonder if it would cycle a semi-auto and, obviously, I want to run some through a suppressor just to see err hear.

    Midway has bricks in stock. I almost ordered some, but $10 to ship one brick of ammo is insane – and there’s not enough in the fun fund to buy other stuff I want. 😉

    There is also Aquila Colibri (a modern take on the CB cap):

    And if you want to suppress a shotgun (72db @100ft) without a suppressor:

    That would be *EXCELLENT* for new shooters.

    I will have to find some.

    Thanks Unc!

    The article says they achieve the low noise level by mimicking a .22 short. Why not simply use a .22 short? Gotta be cheaper than a specialty round.

  5. CTone Says:

    Be careful shooting these, CB shorts, or the Super Collibris in rifles. Yes, they’re very quiet, but sometimes the bullet can get stuck in the barrel –

    I chronographed those rounds that day at 650ish fps out of that 18″ barrel, which is close to the advertised velocity of the Quiet 22s.

    Just an FYI.

    22 Shorts and CB caps are both plenty darn loud; you are losing the supersonic “CRACK” with the slower rounds, but quite a bit of the “BANG” remains.

  7. Mr Evilwrench Says:

    The Colibris have no powder; they’re just using the primer, so they’re likely to squib in anything but a pistol.

  8. Oleg Volk Says:

    At SHOT, they said the trick was in using up the powder before the bullet clears the muzzle — so no flash and very little noise. NOT recommended for suppressed use as there’s almost no difference in the sound signature.

  9. ZerCool Says:

    To those saying “why not use a short” (or CB), the answer is simple: proper feeding from a magazine.
    My bolt gun won’t feed .22S/L properly – the round is out of the mag lips before the nose has reached the chamber, and it ends up flopping around in the ejection port.

    A pump or lever .22 will work fine with S/L/LR, but bolt guns get picky.

    How long before the Brady Bunch goes into PSH to have these “Assassin Bullets” pulled off the market?

  11. dg1013 Says:

    The rep at SHOT show said they WILL NOT cycle a semi-auto. Or they may only cycle enough to eject the empty, but not enough to feed the next round.

    you could probably put in a weaker spring or lighten the slide though to make it cycle correctly.

  12. Will Says:

    IIRC, in a barrel cutting test, 11 inches was what a 22LR needed to burn all it’s powder. Any additional length just caused the bullet to slow down due to friction. Can’t recall if they tested the shorter cartridges in the same test.

Remember, I do this to entertain me, not you.
