I have been having no luck with Czech surpluss in my xcr. Failure to eject failure to feed and having to run my rifle on the highest gas setting. My Canada ammo non corrosive case showed up and I couldn't be happier. Flawless feed and eject and my XCR is now on gas setting 2. Also an average 3 inch 10 shot group at 100 yds using an elcan for optic. So thanks Canada Ammo for saving me a pile of gun smith time!
