Abstract: A projectile system has a projectile with a metal body having a first outside diameter, a forward end and a rearward end, a plastic base wad engaged at the rearward end, the plastic base wad of solid plastic having a first length and a second outside diameter, greater than the first outside diameter, and a rifled barrel having a third inside diameter at the tips of the rifling, the third inside diameter greater than the first outside diameter but less than the second outside diameter, and a fourth diameter at the root of the rifling greater than the second outside diameter. With the projectile translating along the rifled barrel, the metal body passes inside the rifling, avoiding metal to metal friction, while the plastic base wad fully engages the rifling, imparting rotation to the metal projectile.

Abstract: A projectile device is disclosed for firing at a target. The projectile device includes a shroud, the shroud having a forward end and a rearward end. The shroud defines a channel which extends through the shroud between the forward end and the rearward end of the shroud. An insert is releasably secured to the shroud such that after the forward end of the shroud strikes the target, the insert is released from the shroud for increasing penetration of the shroud through the target.
