The Federal Premium loads start with the finest primers, which are subjected to more frequent inspections for dimensional tolerances and charge weight to ensure they deliver consistent ignition for every shot. Next is the propellants, which are specially formulated to meet Federal's stringent specifications. These clean-burning powders are of the highest grades in the industry. They're consistent and reliable. The Heavyweight TSS payloads of heavyweight Tungsten Super Shot provide the highest pellet counts possible. The tungsten-alloy material's 18 gm/cc density is 22 percent higher than standard tungsten and 56 percent more than lead. The result is the most energy and highest velocities at extreme range. Its rear-braking FLITECONTROL FLEX wad performs flawlessly through ported and standard turkey chokes for the most consistent, deadly patterns possible.
