Actually, quite a few weapons can be called self-loading, even those with magazines.
Self Loading - definition from The Machine Gun, Osprey pulications, weapons series -
a weapon which through means on an internal mechanism, powered by either gases of combustion or mechanical spring system, ejects the current (now empty) cartridge shell out of the chamber, whilst loading a new round of ammunition into the chamger, readying the weapon to fire once more. Ammunition may be taken from (external) magazines, clips/belts/chains of ammunition or a 'stripper clip' placed into an internal (fixed) magazine
