It's a velocity issue. The typical full WC load seems to be right on the edge of stabilization. Some guns are faster than others. So, a fast 4" gun and they shoot fine at 50 yards. I've seen them shoot shotgun patterns at 10 yards out of a snub. The same snub shot a fist sized group at 25 yards with a standard LRN load running 100 fps faster. If you handload the WC's to a higher velocity, they will likely stabilize at longer ranges.
FWIW, in official PPC competition, the NRA rules prohibit full WC's. They do allow them in Bullseye and they shoot to 50 yards in Bullseye.
