I haven't heard of this problem in Senderos in the past but that is certainly a possibility. Before jumping too far I'd have a gunsmith check it out.
Years ago I had a 700bdl 7mm Mag that had this problem and it was due to the bolt face being improperly finished. It just needed a small bit of cleaning out and it functioned perfectly from then on.
OP take a look at your bolt face, do you see any brass shavings stuck in it?
