Federal collaborated with legendary choke designer Rob Roberts on these powerful limited-edition loads. Both the 7 and 9 shot offerings are Roberts' personal favorites. The No. 7 payload delivers his ideal balance of pattern efficiency and long-range power that flattens hung-up gobblers, while the No. 9 maxes out pellet counts for the ultimate pattern density. Like all Federal PremiumA(R) HEAVYWEIGHT TSS options, the loads feature 18 g/cc tungsten-alloy shot that's 56 percent denser than lead for the highest pellet counts and the most energy at extreme range. The rear-braking FLITECONTROL FLEX wad performs flawlessly through ported and standard turkey chokes for consistent, deadly patterns.
