Tungsten Super Shot has been a cult favorite among turkey hunting nuts for several years, but it went mainstream in a big way last spring with the introduction of Federal Heavyweight TSS. The stuff is expensive, but after dumping gobblers at 50-plus yards with TSS No. 9 shot, many hunters—myself included—wondered, "How would this stuff do on ducks?" TSS is non-toxic, but cost prohibitive for high-volume shooting. So, to keep costs down, Federal blended it with their proven Flight Stopper steel to create a new Black Cloud TSS shell that is off-the-charts effective. I used it on a DIY duck hunt in North Dakota last fall, and it flat works. I'm not a fan of shooting ducks—or anything else—at long range, but sometimes stuff happens and that third shot in the gun is often at a 50-plus-yard bird. These shells have the pellet count and ballistics to do the job at that range and probably farther. The 3-inch,1¼-ounce loads match either No. 7 or No. 9 TSS (60 percent of the shot) with BB or No. 3 steel (40 percent). At almost $38 for 10, they aren't cheap, but they aren't out of touch with other high-performance waterfowl loads, either. $37.95 for box of 10; federalpremium.com —W.B.
