  • Yes, you read the extreme spread correct, 171 fps separated the slowest from fastest.
  • Accuracy wasn’t horrible for having such high SD and ES.
  • Suspect the accuracy will suffer at long ranges with such a large spread of velocity.

  • Again, the extreme spread was way up there in the Tango as well.
  • The SD was better than in the SC1, but accuracy was even worse.
  • Velocity from the shorter 20″ was nearly as high as with the SC1

NOTE: “Accuracy with flyers” includes the raw averages including groups where the shooter called a bad shot before rechecking the placement of that shot. The “average without flyers” is the average group size with those “flyer” groups not added in.
