FX IMPACT BACK FROM AOA!!!!!! I'M IN LOVE!!

Frank, that is some excellent shooting! I think you found a rifle that suits you well. :) Thanks for sharing!

If I may make some suggestions... Use the calipers to measure your return level knob. I measure mine from the shoulder to the knob bottom. Write that down. Then mark your power wheel. I found that my two level 4's shoot at different speeds. I think that's why the newer models come with numbers and letters. Regardless, mark it/take a picture/write it down. Then take a picture and count the protruding threads of the power adjustment fine tuning setscrew. Write that down. Finally, take a pic of your regulator setting. Maybe even go so far as to put a tiny mark on the adjustment screw. While your at it, take a close up of your setscrews on your trigger. You can get a real nice shot by removing the trigger guard and it won't effect anything.
Your rifle is shooting superb! You'll want to know what all those setting were if you ever decide to fiddle around with it. 
Happy Shooting!
Tom
