Case not ejecting on a fired round

[Stugotz]

I got a chance to sneak away from work this afternoon and chrono some loads for my hog hunt down in Tx this January. On a positive note, all of my loads grouped 1 MOA or less. The BCG is still not coming out of battery enough to eject the spent shell casing. (Adj gas block cranked wide open). I asked a fellow shooter to video the action while I took a shot down range and just watched the vid. As I stated, the action is opening. I went through the vid frame by frame and estimate the action opens approx. 1.35-1.4". I live about 40 miles south of JP Enterprises and plan on making a trip up to their offices (Silent Captured Spring in tow) and asking them if they can break it down reducing the weight of it and seeing if that will make a difference...
