If you’ve already taken my advice and purchased yourself a 22 LR rifle (like the Ruger 10/22 which is my favorite) or already have one, you probably love how quiet the 22LR rounds are compared to most other ammunition. But despite being relatively quiet, they are still noticeable to within a few hundred yards by others around you.
While not as powerful or accurate over long range as the 22LR round, it is still powerful enough to take small game such as rabbit or squirrel and provides the added advantage of being no louder than a pellet gun (and perhaps even less so). The reason for its silence is due to its minute propellant charge (in many cases it’s just the primer with no gunpowder) which results in a low muzzle velocity of around 700 ft/s (subsonic).
The advantages of this kind of round in a serious survival situation (urban or wilderness) are obvious. With a report no louder than a pellet gun, the .22 CB Cap round gives you the benefit of being able to easily take smaller game — even in a congested urban area — without anyone the wiser (Pigeon anyone? yummy…). It also allows for target practice without bothering the pesky neighbors.
One of the main disadvantages of the .22 CB Cap is that it won’t cycle most semi-automatic firearms. Since the round doesn’t provide enough power to cycle the bolt, each round must be fed manually, one at a time. Despite this major disadvantage I still highly recommend adding a box or two of .22 CB Cap to your store (and some for your second tier kit while your at it) when silence is of primary importance.
