There's a fix for that. Google up "Mosin sticky bolt syndrome" and there's a couple of YouTubes which cover it.
I don't own any Mausers, they're a little steep for the Lurker arsenal right now. Besides I want to stay standard on as many calibers as I can. So it'll be the Mosin's and tins of ammo for the forseeable future I think.
But like I said, had I bought half a dozen of those Ishapores when I had the chance.....
