Jerry Keefer (RIP) apparently wasn't a fan of the 1:18 3/4" twist rate of the S&W model 52 stock barrel. He said that PPC revolvers generally used a twist rate of 1:10- 1:14 and those faster twist rates showed sub 1" groups at 50 yards with no bullet tipping. Looks like Clark might have decided that the faster twist rate might be better for the 52.
