I have a Mauser that shoots 8mm and I have shot this gun before without any loading or cocking problems

when I took the gun to the range last time, this happened

 
Your rifle's extractor isn't made to bend up and over the rim of the cartridge. You may even break it by forcing it.

Your Yugo bolt is like most milspec Mausers designed for "controlled round feed."

That means it needs the bullet rim to slip between the face of the bolt and the extractor to come into locked up battery.

In your video, the cartridge is fed in front of the extractor and the extractor can't bend up and over it.

You may be able to find an extractor that has been ground to do this or pay a smith that knows what they're doing, to grind it properly to function the way you want it to. That can have all sorts of negative issues, if the job isn't done properly.

Your chambering problem is caused by OPERATOR ERROR
 
Yup, you're using it wrong. For the vast majority of Controlled Round Feed (CRF, or Mauser style Claw extractor) you must ONLY feed round from the magazine. Single feeding them bends, and will eventually break the extractor.
 
An experienced gunsmith should be able to alter your extractor so you can chamber a round and then close the bolt... thousands have been done...
 
Commercial mausers like my CZ 550's and Zastava LKM70's chamber rounds ok push fed. Same with my Ruger Hawkeye's. If I want to try it. But generally don't need to.
 
The proper way to single load like that is to put pressure on the middle of the extractor with the finger tips of your left hand. This will lift the extractor a hair so it can go over the case rim without damage.
 
The first thing you need to look at if you want to "push feed" with a Mauser style extractor, is if the barrel, at the breech, has a "clearance cut" made to it to allow room for the extractor to move over the rim. This clearance cut needs to be made before any extractor of this type will work.

No not on a mauser action.
All that is required is some fine tuning of the extractor.

That would work if there is enough clearance in the receiver but that method requires strong hands and is awkward IMHO.

I have an old friend that does exactly what you describe and did it as slick and smooth as could be, until last year. He's 75 this year and the Arthritis in his left hand made the procedure impossible. He ended up dropping the rifle onto its scope and of course a handy rock had to be where it fell.

Luckily I had an old scope, that was identical to the buggered one on my scope shelf. It was a quick swap and sight in and a chance to return a favor to a valued friend.

I also tuned his extractor, so it would slip over the cartridge, when fed singly. That's not a job that should be done by inexperienced hands, without a mentor. More to it than just a bit of grinding. Lots of removing very small amounts of metal until it works fairly easily and polishing the surfaces to help it work easily. Take off to much and a new extractor is the only fix.

Yep! Showed a few people how to do that over the years, and sure enough it has become more difficult. Now, I just tell them how to do it, and watch and coach until they get it done. :)

... or you could just load from the magazine the way it's supposed to be done.

Certainly, that's the way it should be done. However, it's nice to know how to get the extractor over the rim if someone ends up with a round stuck in the chamber 120 miles down a river or on the side of a mountain somewhere. ;)

Had that happen a few times while guiding.

All that is needed is to match the rim of the case to the chamfer on the extractor and bingo the extractor rides smoothly over the cartridge in the chamber.I have done literally hundreds with no issue .I was a Mauser nut for years.Most commercial mausers are modified at the factory to do this .Note there is no clearance modifications on the receiver required as previously stated

My first run in with one that had clearance issues was with a Turk with a large ring receiver but threaded for a small ring barrel. I have one here that needs more modification than just a grind job.
