Josey, no, they are current production ammo produced by CCI. They are from all appearances the same as a short but do not have quite so large a powder charge. I believe the ones you refer to are properly called CB Caps as opposed to CB Shorts.

FWIW, the market production of reduced loads (quieter) has grown greatly in the last few years and aside from the European production of BB and CB Caps, Winchester, Remington, CCI and probably some others are producing a wide array of "CB" ammo and other subsonic ammo. So far as performance, the LR based versions will likely provide better penetration if they are a RN form and not hollow point. The noise associated with any of this ammo is directly related to barrel length.

I am..........disturbed.
