Nothing brings out the performance of firearms like HEVI-Shot pellets and now the makers of the revolutionary pellet, ENVIRON-Metal, Inc., are making their own shells that include great features such as weather-resistant crimps. Take out coyotes from distances that you wouldn't think possible with the Hevi-Shot Dead Coyote! Shotshells. The shells give a 100-percent pattern at 40 yards and lethal knockdown patterns at 70-plus yards. To help give that ''knockdown pattern,'' every load includes 50-plus .20 caliber ''T-shot'' pellets. 12 gauge. 10 rounds per box.
