At the range today, I shot some PPU 45gr soft point ammunition. It shot well, but three out of twenty did not extract when I operated the bolt. I closed the bolt and tried a couple of times to get the brass to extract, but that didn't work. I have a short length, approximately 6 inches, of brass road in my shooting bag. I dropped it down the barrel and the empties popped right out, no problem.

On my previous trip to the range, I shot some S & B and some Hornady 35gr ammunition and had no problems with extraction.

Have you experienced similar behavior?
