Tapering (firearms)

In firearms,Tapering refers to components that narrow down, similar to that of a conical fashion hence the name taper. In barrels, this centralises mass to the operator. Not only to reduce weight from the muzzle but also to increase accuracy and stabilise the balance handling of the weapon. Also the fact that chamber pressures are higher at the rear of the barrel. In cartridges, this usually helps in chambering/unloading the weapon. This differs than bottlenecking as this only refers to the case head of the cartridge that holds the projectile, wheras tapering usually refers to the angled sides of the cartridge.
