Many governments and companies continue to develop caseless ammunition {{Citation needed|date=April 2014}} (where the entire case assembly is either consumed when the round fires or whatever remains is ejected with the bullet). So far, none has been successful enough to reach the civilian market and gain commercial success. Even within the military market, use is limited. Around 1848, [[Sharps Rifle Manufacturing Company|Sharps]] introduced a rifle and paper cartridge (containing everything but the primer) system. When new, these guns had significant gas leaks at the chamber end, and with use these leaks progressively worsened. This problem plagues caseless cartridges and gun systems to this day.

The [[Daisy V/L|Daisy Heddon VL Single Shot Rifle]], which used a caseless round in .22 caliber, was produced by the air gun company, beginning in 1968. Apparently, Daisy never considered the gun an actual firearm. In 1969, the ATF ruled it was in fact a firearm, which Daisy was not licensed to produce. Production of the guns and the ammo was discontinued in 1969. They are still available on the secondary market, mainly as collector items, as most owners report that accuracy is not very good.<ref>{{Cite web |url=http://everything2.com/title/Daisy+V%252FL |title=Daisy V/L |access-date=3 October 2013 |archive-url=https://web.archive.org/web/20131005223625/http://everything2.com/title/Daisy+V%252FL |archive-date=5 October 2013 |url-status=live }}</ref>

In 1989, [[Heckler & Koch]], a prominent German firearms manufacturer, began advertising the [[G11 assault rifle]], which shot a 4.73×33 square caseless round. The round was mechanically fired, with an integral primer.{{Citation needed|date=June 2011}}

In 1993 [[Voere]] of Austria began selling a gun and caseless ammunition. Their system used a primer, [[electronic firing|electronically fired]] at 17.5 ± 2 [[volt]]s. The upper and lower limits prevent fire from either stray currents or [[static electricity]]. The direct electrical firing eliminates the mechanical delays associated with a striker, reducing [[lock time]] and allowing for easier adjustment of the rifle trigger.{{Citation needed|date=June 2011}}

In both instances, the "case" was molded directly from solid [[nitrocellulose]], which is itself relatively strong and inert. The bullet and primer were glued into the propellant block.{{Citation needed|date=June 2011}}
