Rim cartridges are cartridges with a protruding edge at the bottom of the case that prevents the cartridge from sliding forward in the chamber. Edge cartridges with Central or rimfire made.


The first metal black powder cartridges were all designed as rim cartridges ( Flobert cartridge , .44 Henry for the Henry rifle , .577 Snider for the Snider-Enfield Rifle , .577-.450 Martini-Henry for the Martini-Henry rifle , 11 × 60 mm R or 10.4 mm Vetterli ).

The first cartridge designed purely for nitro propellant powder , the 8 mm Lebel for the Lebel rifle , also had a rim.

With the introduction of cartridges with an extractor groove , rim cartridges (recognizable by the R in the designation) moved into the background and are now mostly found in hunting weapons and revolvers.


Occasionally there are cartridges with and without a rim for the same barrel caliber, e.g. B. 8 × 57 mm IS or 8 × 57 mm IRS. In most cases it is a bottle neck cartridge . The only difference is in the pull-out groove or in the edge. The IRS cartridge is used in drop barrel weapons.

In sport shooting with ordinance weapons, weapons with rim cartridges are still used today, e.g. E.g. the .303 British for the various models of the Lee-Enfield rifle. The Russian cartridge 7.62 × 54 mm R is still in military use .

The rim cartridge most widely used in the world is the rimfire small bore cartridge .22 lfB , which is used in shooting and trapping.

Rim cartridges form the breech gap on the face of the rim.
