Venture extractor does not reliably hold. In both my 270 WSM and my .204 Ruger, extractor quite regularly FTE. Pull bolt back, no brass.
If the extractor doesn't pull fired brass out of the chamber, the gun is BROKEN, and if under warranty, should be repaired by the maker. PERIOD.
usually easiest to just replace the extractor yourself, but you need to have a replacement. Even in the finest of arms, its is possible for the extractor to break and fail at any time. It SHOULD be good for tens of thousands of cycles but it might not be, and no one can tell you for certain if/when it will fail.
I got one of the semi auto Tommyguns, used. Gun looked new, clearly it had not been shot very much, The 3rd mag through it, the extractor broke, and it was done. I ordered a replacement. Actually 2 of them. Put one in the bolt, and the other in the buttrap as "on board spare" About a decade later, and a few thousand rounds without issue, I sent the gun to my son, because he asked for it. Its now several years later, and no issues.
in the early 70s I had a Remington 600 that got damaged due to an overload. Gunsmith fixed it, but it needed an extractor and none were available at the time, from Rem. Gunsmith made one. Worked fine until the gun was fired and then left the fired case in the chamber. Took about a month but the gunsmith got a Rem extractor and put it in. Rifle has been fine, ever since (I still have it).
In the early 80s Wife got a Savage 110CL .30-06 (on the advice of a friend, only time she didn't listen to me about guns...
) fired about half a box of shells and the extractor stopped working. Ordered one from Savage, took a month or so. I installed it and it worked. Gun was then sold, as the 06 was just too much gun for her.
I've never seen a Mauser 98 extractor that was worn out, but I have seen some that were broken.
IF you want to keep your bolt gun running until the barrel is shot out (and beyond) get a spare extractor, and a set of all the springs to have on hand, jut in case.
