not soaking wet but good film of lube. We only shot maybe 80-100 rdsAre you running the BCG fairly wet? Not sure on the Mil-Spec primers. Probably harder than the regular ones. Does BCA use extended tip firing pins? I have some green lacquered Wolf Mil-Spec (Barnaul) that didn't want to go bang in an AR47. Good solid hits. They didn't go bang on several.
Not sure on the ejection patterns.
