Hornady Superformance 257 Weatherby Magnum Rifle Ammunition features a 86 grain gilding metal expanding bullet. Hornady superformance ammunition uses proprietary propellants that increase velocity up to 200 feet per second more than comparable loads. The increase in velocity is not a product of increased pressure, and as such, there is no increase in recoil. Hornady increases the efficiency and accuracy of their match grade and superformance ammunition each year and as a result they help more people win shooting tournaments each year.
