Tungsten Super Shot (TSS) has a 22% heavier density than heavyweight shot and a 56% heavier density than traditional lead shot.
The denser the shot, the better it retains velocity, the harder it hits, the smaller the shot size you can use, the tighter it patterns—and the better it drops turkey, ducks, and pheasant.
"Killed a ton of geese over the years but today I shot my first triple. Did it with my A400 28ga shooting the TSS 9's. They kept fallin so I kept shooting.
9's ain't no joke. My daughter with 28 grains of powder and 9's in her SA20 at a 35 or so."
TSS is a more humane and ethical shot to shoot - period. Less chance of cripples, and leaves them in amazing shape for taxidermy
