Synonyms 7.62 × 33 `T'; 7.62 mm Spanish Regaña; 7.62 mm Modelo 68; 7.62mm subcalibre Armament Subcalibre inserts for the 88.9 mm Instalaza M-65 anti-tank rocket launcher used by the Spanish and other armies. Development This cartridge was developed in 1968 by Colonel Regaña of the Spanish Army. It was originally based on a 7.92 × 33 mm Kurz case necked down to take a 7.62 × 51 mm NATO tracer bullet, providing a suitable cartridge for the subcalibre training device. Description Although using the same metric
notation, this round should not be confused with the 7.62 × 33 mm 0.30 Carbine cartridge described previously. The two completely different and cannot be interchanged. The round consists of a pointed rifle-type tracer bullet fitted into a cut down and necked 7.62 × 51 mm cartridge case. The bullet and propelling charge are designed to reproduce the trajectory of the anti-tank rocket fired from the parent weapon. A 7.62 mm calibre barrel is inserted into the rocket launcher tube in the form of a dummy rocket which is loaded in the same fashion as a live round. The firing circuit is arranged to fire the cartridge, after which the dummy rocket is removed and a fresh one loaded. The bullet displays a visible trace which permits its flight to be tracked for instructional purposes.
