Winchester Last Call TSS Features The Winchester Last Call TSS load is buffered to protect the dense 18 g/cc tungsten shot from deformation as it travels down the barrel preserving pellet roundness for tighter downrange patterns. This buffering matters because deformed pellets fly erratically and open patterns prematurely costing hunters clean opportunities at longer range. The tungsten super shot material packs more pellets into the same payload weight than lead or steel filling the kill zone with a denser more inescapable pattern. Winchester built this load specifically to exceed the demands of elite waterfowl and turkey hunters who refuse to compromise on lethality. Ten rounds per box gives turkey hunters a practical supply for patterning a shotgun choke combination before opening day and still having rounds left for the hunt itself. The 1350 fps velocity keeps the tight TSS pattern moving fast enough to deliver reliable knockdown power at the ranges turkey hunters commonly encounter. For hunters chasing tom turkeys with a .410 shotgun who want the tightest most consistent pattern available Last Call TSS represents the top tier of turkey ammunition technology.
