Another cartridge conversion was the Pedersen device, which was designed to convert the bolt action Springfield 1903 Mark I into a 40 shot blowback semi-automatic firearm chambering a lengthened version of the .32 ACP cartridge. The 1903 Mark I differed from the standard rifle in that it had a slot cut in one side of the receiver, which served ...
The caliber conversion sleeves resemble fired cartridge cases in the rifle calibers for which they are made, but are made of steel instead of brass, and have an opening where the primer would normally sit into which the 32 ACP cartridge is inserted, prior to chambering the combined 32 ACP round and caliber conversion sleeve in the rifle.

The external cartridge case dimensions like overall length and slightly larger case head diameter compared to the German 8×57mm IS military cartridge coupled with a moderate increase in maximum pressure were chosen with easy conversion of Gewehr 98 rifles for the 8×64mm S in mind. Brenneke hoped that he could achieve a major success with this ...
The 6.8mm Remington Special Purpose Cartridge (6.8 SPC, 6.8 SPC II or 6.8×43mm) is a rimless bottlenecked intermediate rifle cartridge that was developed by Remington Arms in collaboration with members of the U.S. Army Marksmanship Unit and United States Special Operations Command [6] to possibly replace the 5.56 NATO cartridge in short barreled rifles (SBR) and carbines.
The widespread availability of standard size Mauser 98 rifles and the fact that the .375 H&H Magnum cartridge and its necked down version the .300 H&H Magnum with approximately 72 mm (2.83 in) case length were too long to fit in standard sized Mauser 98 bolt-action rifles makes the shorter 8×68mm S, 6.5×68mm and .375 Hölderlin interesting ...
In effect, the "device" was essentially a complete blowback pistol minus a receiver-grip using the short "barrel" of the device to fit into the longer chamber of the M1903 rifle. The mechanism was fed by a long 40-round magazine sticking perpendicularly out of the rifle at a 45-degree angle to the top right, and could be reloaded by inserting a ...
The .454 Casull was finally commercialized in 1997, when SAAMI published its first standards for the cartridge. [6] [7] [8] The new Casull round uses a small rifle primer rather than a pistol primer, because it develops extremely high chamber pressures of over 50,000 CUP (copper units of pressure) (410 MPa), which are rifle levels of pressure ...
