Spuhr mount TROUBLES

no pics at the moment, droped rifle off at smith thinking i had ejector problems but smith called and told me that the brass was hitting the mount. will pic up this weekend and check it out myself in depth.
 
It may be hitting the mount but I can't fathom any way the mount could be the problem. I have two Surgeon 591's with Spuhr mounts and no problems relegated to brass ejection. The base attachment with the Spuhr has a narrower profile than rings with a cross bolt, if ejected cases are hitting the mount it's another problem, My guess is it's either the extractor or possibly the ejector..........................
 
my buddy had a tikka in a xlr carbon chassis and he had the same problem when running the bolt quickly. When he went slow there was no issue. The tikka had a 20 moa rail. my bighorn in an aiax aics chassis did not have any issues with their 20 moa rail.
 
FYI, the 300wsm brass is hitting the mount when ejecting nocking it back in. seems that this particular setup surgeon 591sa magnum with this spuhr mount(5001) is not compatible being the angle of the 300wsm brass coming out is striking the mount. hope this helps someone in the future.
