I am a believer in the Tikka T-1X, for an out of the box plug and play squirrel rifle I don't know what would be better in its price range.
The large dark lines are one-inch apart and lighter colored lines are 1/4" apart.
All three groups measure right at 1/2" inch center to center - it would have been nice if I had not dropped one a bit low on the left-hand target but I am still happy with the results.
