The ZRG-20mm refers to a large-caliber, bolt-action anti-materiel rifle chambered for the 20mm Vulcan round. Its practical applications include long-range target shooting, extreme hunting of large game, and limited military roles where extreme penetration is required. Examples include disabling light armored vehicles or disrupting sensitive equipment at significant distances.
The significant power of this cartridge allows for unparalleled performance in terms of kinetic energy delivery. This translates to substantial stopping power and effective range exceeding that of most conventional rifle calibers. Historically, the development of such powerful firearms reflects an ongoing advancement in ammunition and weapons technology, driven by the need for increased lethality and range. This power, however, necessitates careful handling and specialized training for safe and effective operation.
