Anyone know what this is?

... and some I cant. LOL The Daisy caseless system was basically a piston air rifle that rather than shooting a pellet used the compressed air jet (2000 deg. F) to ignite this unique ammo designed by a Belgian. Essentially a 29 gr. .22 Short bullet with little appendages off the back so the powder pellet can be glued. You could not carry them loose in the pocket, as the powder pellet would likely fall off eventually) so they devised these little tubes carrying (10) each. A box contained 10 or 100 rnds. The bullet ran 1150 fps the same as a high velocity .22 Short. there was nothing to eject and it was completely reliable and clean shooting. You simply opened the airgun cocking lever, put a round in the breach, close the lever, flicked off the auto safety and fired. It was the first and only commercially successful caseless round developed so far and made in only 1967-68. The ATF closed it down as Daisy had no firearm manufacturing license and they declared the air-rifle a "Gun" based on the ammo. Technically to them it was a "gun" using an air ignition system. That put a stop to the Daisy VL rifle series. Denning and I both probably have wondered how to stick 2-3 powder nuggets in there. Daisy thought of that with a stepped chamber making that unlikely. They should bring the idea back. What a novel idea, and it worked!
