Major Kinetic Energy. The first all-steel shotshell from HEVI-Shot is pushed out at a blistering 1500fps, compared to competing fast steel loads, which run at 1450fps (12g 3" 1.25oz). This increase in speed delivers 9% more energy at 30 yards and 8% at 40! In short, you will get more knockdown power and fewer crippled birds. Combining higher velocity, a best-in-class wad and precision manufacturing techniques delivers the ultimate in performance. HEVI-Steel hits hard every time!
