The Soviet PTRD 14.5×114mm anti-tank rifle also used a bolt based on the Mauser Gewehr 98 rifle, as this design is legendary for its strength and simplicity and has become the most widely adopted and copied designs of all time. The Wz. 35 is itself inspired by the 13.2mm TuF anti-tank rifle, also a scaled-up G98 rifle. The main difference is that while the TuF and PTRD were chambered in a large-caliber round, the Wz. 35 used an oversized cartridge case mated to a rifle-caliber 8mm bullet, giving very high velocity at the expense of hitting power. The Panzerbüchse 39 also used an 8mm bullet, but with an out-sized 8mm Mauser cartridge case known as the 7.92x94mm Patronen, and a special tool-steel cored bullet.
