Description
Federal Grand Slam shells pair proven lead performance with smart wad design to keep more pellets on target where it matters. The 2-ounce #6 payload travels at 1200 fps and relies on the FLITECONTROL FLEX wad system to control the shot release as it exits the muzzle. This rear-opening wad design stays with the shot column longer than conventional wads, which means you get consistent, dense patterns through both standard and ported turkey chokes.
What makes Grand Slam different is the buffering compound protecting your pellets. Copper-plated lead shot can get deformed during the stress of firing, which scatters your pattern and wastes pellets. The advanced buffer cushions each pellet to keep them round and uniform, reducing flyers and keeping more hits in the 10-inch circle where turkeys need to go down.
Grand Slam for Effective Range
These 3.5-inch shells give you the full payload and velocity to reach turkeys at extended distances. The combination of 2 ounces of #6 shot with the FLITECONTROL FLEX system delivers the kind of pattern density that lets you take confident shots beyond typical ranges. The copper-plated construction means better penetration and more reliable terminal performance on birds at distance.
Why Grand Slam Works in Any Choke
The FLITECONTROL FLEX wad system was designed to work with all turkey chokes, including the newer wad-stripping models that are becoming increasingly popular. You get consistent results whether you're shooting a standard full choke or a dedicated turkey choke with ports. That flexibility means you can pattern test and hunt without worrying about whether your gun setup will work.

Frequently Asked Questions
Will Federal Grand Slam shells work in my turkey shotgun with a ported choke?
Yes. The FLITECONTROL FLEX wad system is specifically engineered to work in both standard and ported chokes, including the newer wad-stripping models. It opens from the rear to control the shot release and maintains consistent patterns regardless of choke type.
What shot size should I choose between #6 and other options in the Grand Slam line?
Number 6 shot is a proven gobbler killer and works well for all-around turkey hunting. The smaller pellets create a denser pattern at typical turkey ranges. Number 5 offers slightly fewer but heavier pellets for extended-range work. It comes down to your gun's patterns and where you hunt most often.
Why does Federal use buffering in Grand Slam loads?
The buffering compound cushions pellets during the firing process to prevent deformation and flattening. When pellets lose their round shape, they don't fly straight and scatter out of your pattern. Maintaining that round shape keeps more pellets in the core of your pattern where they need to be for ethical turkey hunting.
Can I pattern test Federal Grand Slam before the season?
Absolutely. Pattern testing is one of the best ways to prepare for turkey season. These shells give you repeatable, consistent results, so your bench patterns will translate well to field performance once you find the choke and distance that works best for your gun.
