Premium V-Shok Rimfire ammunition is useful for everything from plinking to varmint or small-game hunting. Each round provides the shooter explosive disruption so it's perfect for competition or an afternoon on the prairie. This ammunition is new production and non-corrosive. Speer TNT bullets feature soft lead cores and precision-drawn jackets fluted over 90% of their length for rapid expansion and complete disruption, even in cartridges with modest velocities. These bullets also offer a minimum bearing surface which creates a bullet with a long nose and trajectories that rival those of bullets of similar weight, making these the perfect varmint eliminating bullet.
