It is my understanding that 22 mag and 22LR both are a 1:16 twist rate. I haven any experience with 22mag, but a friend showed me targets from 3 he was shooting. A S&W, a High Standard, and a Taurus. The Taurus was a 4" barrel, nearly new gun, but groups were poor and numerous keyholes. Shot at 10 yards, about 4" groups and probably 75% of the rounds at least partially sideways. The S&W and High Standard both shot nicely.
Would it make sense that a higher velocity, and short barrel may be causing this? The bore is good, clean and crisp rifling, crown looks fine. B/C gap is minimal, maybe in the .003 -.004 range.
Have 22 mags ever been made with other than 1:16?
What else should we be looking for?
