One Cartridge, not a box: .30 Salvo Squeeze Bore” 30 SSB “Triplex”Military Experimental by Colt, very limited, never in mass production.History of the  Colt 30 Salvo Squeeze Bore or 30 SSB is a very rare experimental cartridge with three projectiles within the case neck, which was developed by Colt in the late 1960’s to early 70s and based on the original invention of  Russ Robinson in 1903. Russ had observed that squeezing multiple-stacked-projectile rounds would cause them to reliably separate due to air trapped between them. In this application, special tapered muzzles were developed for the M60 Machine Gun.With each shot, the three (55 grain .22 caliber) projectiles would emerge from the muzzle of the firearm and spread out to in crease the probability of hitting the target.The rounds were fabricated at the Colt Research Center using commercial Remington 30-06 cases, increasing the length of the neck to hold the three nested projectiles (similar to photo shown).As you can see from the markings on the box, each one was test chambered for fit and reliability in a specially chambered M-1 Garand rifle , which puts a small dimple on the primer by inertiawhen the firing pin comes forward. The experiment was dropped after a few years as the U.S. Armed Forces lost interest in the project.These was never in mass production of this cartridge and these are truly a rare find, and we only have a few available.
