I know you asked for 3" but I just patterned a bunch of random 3.5 #5 lead, with a sore shoulder. Setup was a 935 with .675 Indian Creek, 40 yards, and my best pattern other than Longbeard XR was my Federal Mag-Shok (pre Flight Control Wad) at 128 hits in a 10" circle. The coverage looked great too.
