I just aquired a Czech (captured?) Kar98k at an auction sale and I'm having trouble chambering a round. I'm certain it's still in 8mm Mauser, the numbers match on all parts, and the bore is pristine. But when I try chambering a round from the magazine, the bullet gets stuck so that about the back 1/3 of the round is still visible before I can't go any further, so then I could drop a round straight down the chamber and it'll appear to have gone all the way in, but when I try closing on it, the bolt only turns about 40° or so before it stops, but I assume it's the extractor not getting around the lip.
Is this a head space issue or is there maybe a piece of an old case stuck inside the chamber? I tried taking a flash light and looking but I can't see inside of it that well. When I do try chambering a round though it gets stuck hard enough to where I need to drop an aluminum cleaning rod down the bore with a little force to make it pop out.
Hopefully you guys know more about the Czech Kar98k's than I do.
