The lead-free SuperSabot’s controlled mushrooming is dependent on its target resistance. It is ideal for use with rifled barrels, however, if you prefer a smooth barrel, chokes must be omitted. The Super Sabot presents 58% more frontal and expands up to an incredible one inch in diameter. Its accuracy rivals many centerfire rifles. The Super Sabot is constructed with an aluminum point, brass jacket/core and a carcass that opens when leaving the barrel.
