Forget my last post... from fedral's website:

FLITECONTROL Wad
For turkey hunters there are new Mag•Shok™ loads featuring the revolutionary FLITECONTROL wad. This unique wad employs a rear-braking system that helps it stay with shot longer (up to 19-feet out of the muzzle in test barrels), choking the pellets into a lethally tight pattern. Plus, Mag•Shok’s copper-plated, buffered lead shot produces dense, tight and uniform patterns. FLITECONTROL will be offered in two shot types, Mag-Shok lead and new Mag-Shok HEAVYWEIGHT—both in 3 and 3-1/2-inch shell lengths and number 4, 5 and 6 shot sizes.

I hope this post doesn't violate forum rules, I'm not pushing a product just correcting my previous post...
