Traditional Czech ammunition manufacturer Sellier & Bellot constantly brings innovative products to the market. One of them is the XRG ammunition in 7×57 JS caliber, which is highly accurate and suitable, for example, for hunting hoofed game.
The XRG Exergy bullets use top materials for their purposes. They are homogeneous tombac bullets, made from a CuZn 10 alloy, with an aluminum tip. A significant advantage is the almost 100% residual mass of the bullet. This means that the damage to the prey will be minimal when using this type of ammunition.
The deformation of the bullet is regular and controlled also thanks to internal longitudinal grooves in the cavity. As a result, only a small hematoma is created around the shot channel. Moreover, no fragments remain in the body of the defeated game. Additionally, the bullet has three external grooves, which along with heat and surface treatments mean reduced barrel load during firing.
