SUPERFORMANCE ammunition is loaded with proprietary propellants that increase the velocity ratings up to 200 feet per second compared to other popular brands. Because there is no increase in pressure, regardless of the caliber, there is no increase in felt recoil but there IS an increase in efficiency and high speed performance. From sub-zero arctic temperatures to almost unbearable desert heat, SUPERFORMANCE ammunition can withstand any hunting condition.
Hard-hitting and deep-penetrating, the GMX bullet combines monolithic construction with pioneering ballistic design to meet the need for a premium, non-traditional bullet. The mono-metal design of the GMX bullet is crafted from a copper alloy. Harder than solid copper, the copper/zinc alloy has been proven to shoot cleaner, foul less, and deliver consistent, even pressure curves. The tough alloy material routinely retains 95% or more of its original weight and expands up to 1.5 times its original diameter. Featuring a long, sleek profile with cannelures, the design reduces the bullet’s overall bearing surface and drag, while achieving some of the highest ballistic coefficients from monolithic, non-traditional bullets. Initiating expansion upon impact, the hard polymer tip drives into the hollow cavity at the front of the bullet, creating a mushroom-style projectile as it travels through the animal. Fully California compatible and appropriate for use in other areas requiring the use of non-traditional bullets, GMX is ideal for any sized game, from antelope to moose. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
