Well took the new finnbear to the range today and had another weird problem. The gun extracted empty cases better it would occasionally hit the receiver at the back of the ejection port and scratch the metal a little bit but that doesnt bother me. What bothered me was the gun would only shoot with a clean barrel and i mean really clean. First three shots i would get a half inch group and then two fliers. I let the barrel cool and didnt clean and shoot again and they wouldnt group again. So i let cool clean again and bam another half inch group. Any ideas? I mean usually a gun shoots better with a fouled barrel.
