An unfired case with the bullet pulled slides in and out of the chamber quite easily. It seats completely in the chamber with no pressure and I can easily pull it out again with just my fingernail. There's no resistance at all.
So I'm short for some reason and the bullet is seating to the point I can't extract it unfired. But I'm still having extraction issues with fired rounds on a round or two in every 3 mags. Even though the chamber is not tight and the bullet is gone.
It's gone from extracting 100% of cheap ammo, but not extracting Lapua at all, to extracting about 95% of Lapua/SK after an extractor swap. My CZ457 shot lights out with an IBI Barrel with a Calfee 4 chamber and it started sticking. I swore up and down the chamber had an issue. Then I swapped bolts with a buddy and it went away. But of course CZ has nonexistant support for that platform and a new extractor can't be had to save your life.
It sounds to me like it should be extracting. I scratch my head that the cheap stuff that mics out to exactly the same everything has never had an issue
I have no idea why they are behaving di
