Prairie Storm will be available at first in 4 shot, 1 1/4-ounce, 2 3/4-inch loads at 1500 fps. They are unnecessarily fast, at least in my recoil-sensitive opinion ("Ringneck Rocket" was the other name the Federal marketing people considered), and I could certainly feel them going off in my lightweight Benelli Montefeltro. They wouldn't be bad to shoot out of a gas gun, though. Besides, speed sells, the name is cool, and they seem to work. I suspect they will develop a cult following like the one that has grown up around the steel Black Cloud.
