Thanks Stonehenge, getting 3025 avg fps.Adjustable Block wide open, Borescoping confirms perfect port alignment. Using Sprinco's lightest "yellow" spring . I am a Fulltime Gunsmith [Vicious Precision TM] ,have built a few hundred plus serious rifles gas,bolt ,lever etc.. Looking like the wilson BC which is V heavy may be a key here. We'll swap out to lighter BC and test.
btw this rifle shoots MOA at 800 w Hndy Match. We finally got some Lapua and Star Grendel Brass and are forming now. I do a Proprietary Modification on AR's that eliminates the rear pin and it's inherent slop and wear.Not the silly deal with a screw to push upper/Lower apart but actually draws the halves together.Zero movement,ends the wear as well. Easily reversable if you wish to return to the stock pin arrangement.Every one we've done resulted in real improvement,usually half a minute ,often more. It is also High Power legal as is no change to rifle's profile. I digress, sorry. Superformance is powder using right now. Thanks for the input and help, Badgersmith
