This was my first attempt at grouping, fist rear, UTG bipod front, scope on 15x. The trigger on the Atomic XR is set much heavier than my Bantam or Compatto. I will be adjusting it lighter this weekend. These groups can only get better once I get more familiar with the gun. Don't know what happened with the flyer in group 3. Yesterday I took 6 sparrows from 25 to 40 yards so it's definitely a capable little gun.
