Federal doesn't sell the FC wads to anyone. I tried almost everything to see if I could load anything that performed similarly to FC. Even using a variety of standard and specialty buckshot chokes, nothing came close. Without FC wads, it's not possible.
Federal killed the two best patterning buckshot loads (8 pellet 00 and the #1 buck), which shows you how the industry works today. Even though some are re-learning how well shotguns perform, Federal doesn't see enough potential sales to keep making them.
I'll keep what I've got, and use my reloads for practice. If worse comes to worse and I want one hole patterns at whatever range, I'll just use slugs.
