Got my XCR to the range for it's first 100rds. The gun is a lot of fun to shoot, and gets much attention from the AR guys. Two things concerned me, though. First, I had 3 FTF's due to light primer strikes. They went bang second time around, so I guess this may go away as the gun breaks-in. The second thing is those cratered primers. No penetrations, no pressure signs, just that odd shallow dimple surrounded by a crater wall. Never seen anything like it, but all my primers were the same. This has been addressed on other threads, with representative pics, but I haven't seen anything definitive on whether or not there's a problem. Is this OK, or is there a firing pin/bolt/headspace/whatever problem?
