The 7.92 × 24.5 mm subcalibre is a synonyms 7.92 mm M388; 7.92 mm Portuguese Regaña Armament Subcalibre insert barrel for the Portuguese service 84 mm anti-tank rocket launcher (the US 3.5 in M20 ). Development Developed by the Portuguese Army technical staff in 1973, based upon the 7.62 mm Spanish Regaña cartridge (described previously). It differs from the Spanish round as it is smaller and uses a unique cartridge case, which may have been developed from tooling used for the 7.65 mm Parabellum cartridge.

Description This round uses a short-necked, rimless cartridge case, specially developed for the design and not cut down from any existing case. It carries a rifle-type tracer bullet with a very long, tapering ogive. The exposed portion of the bullet is only slightly shorter than the cartridge case. The bullet helps teams reproduce the trajectory of the rocket fired from the parent weapon, delivering a trace to the target for initial training purposes. PORTUGAL Manufacturer INDEP Type: Tracer: As above.
