I've had a very occasional fail to extract, but I don't recall it was with any specific ammo. In my case I'm quite sure it was just dirty. You have to keep the two notches that are in the barrel face for the extractor plates to fit into quite clean. The extractors on the bolt also have to be kept clean. It is worthwhile to carefully remove the C-Spring that holds them in place, trying to keep from stretching it. Take note of the orientation of the two plates before removing. The black sharp one goes on the ejection port side.
Also as I recall, the two notches in the spring have to be at the back side to allow the extractor plates to go full forward.
When I remove the plates I stone the sides to be sure they are flat and have no burrs. Push small pieces of paper towel through the slots in the bolt to be sure they are clean. I use automotive throttle body cleaner to spray the front of the bolt slots, and also the notches in the barrel face. I don't put any gun oil on, and depend on the small amount of residual oil in the cleaner. Do the same with the firing pin (plate).
Before I reassemble I scrunch the C spring between my fingers to make it smaller and tighter. It needs to be tight to hold the extractors around the rim, and not slip. Put the firing plate in first, then the C spring trying not to stretch it. Last slide the extractor plates in from the end of the bolt under the spring, one at a time. I find this helps prevent the spring from stretching.
My QA check is to shake the bolt back and forth once assembled. The firing plate should rattle loud and freely. The only part of the bolt that I have found you have to be generous with lube is the black pin at the very back that climbs the ramp when you cock it. If that pin is not lubricated with a grease, it wears flat and you virtually can't lift the bolt. They are cheap to replace, but shouldn't be necessary if you keep a little grease on the pin and ramp.
This has always cured my problem with extraction. I do know others have spent a lot of time polishing the chamber and claim that works. I've shot lots of heavily waxed Lapua ammo and not had a problem. Lapua makes the Wolf ammo and also SK. They seem to use those brand names in the US for some reason.
