German Tapered Bore Projectile or Gerlich Projectile. See PATR 2510(1958), pp Ger 193-R to Ger 195-R (Illustrated)... 

There are two serious disadvantages of the folding skirt projectile. The taper prohibits the use of std ammo in tapered bore guns and also increases tremendously the time costs of producing both gun ammo. 

German Gerlich Projectile. See German Tapered Bore Gun Projectile... 

Two classes of weapon were eventually categorized the taper bore, in which the barrel is tapered evenly from breech to muzzle, and the squeeze bore, in which the barrel was parallel for some distance and then tapered sharply to effect the squeezing of the projectile, finishing as a parallel bore of smaller dimension. 

An alternative design of squeeze bore was one in which a tapered extension was placed on the muzzle of an otherwise conventional gun [see also Salvo Squeezebore (SSB) in this VoiJ. The projectiles used with these two classes were much the same in design, though experience showed that the taper bore shot had to be somewhat stronger in construction than the squeeze bore models owing to the different times thruout which the shells underwent stress in compression...
