Little help here guys..

I believe this is the proper place to post this.
I have a CZ 527 17 Remington.
Gun is great with one problem.. When I pull the bolt back to eject a case I get the bolt half way rearward and the case will pop off the bolt head.. I've taken the bolt apart and polished everything, changed out springs tried different brass thinking maybe its the case rim thickness.. All I can think of is the bolt body needs replaced because the bolt is ground wrong.. Thoughts??

If you remove the bolt and insert a cartridge base onto the bolt face, is there any slop? Is the extractor making full contact with the rim?

When you pull it back fast does it eject ok? Or does this only happen when youre running it slow?

Doesn't matter the speed in which I manipulate the bolt. The case falls off the bolt . I will try and post a small video of the issue

It sounds like not enough tension on the case. Have it diagnosed for sure but if that's the case the part of the extractor that rides in the groove just behind the bolt face need to be taken down a little to create some tension on the case. This is a grind a little and try multiple times job. Not necessarily for the in experienced. The shape of the extractor hook is also important. Any good gunsmith that understands Mauser extractors can handle it.
