I just now got done reprofiling and refinishing my CZ 527 bolt to clear a Burris scope mounted on my rifle today. The medium Warne rings place the scope perfectly, so I didn't want to get high rings. The bolt as it came from the factory was in need of being dehorned anyways, so the reprofiling wasn't a major inconvenience. Just about 1/2 hour with a dremel tool and the "square section" bolt handle root where it meets the bolt knob is now of a rounded section under the front of the knob where the "social finger" engages the bolt upon unlocking. No more razor sharp bolt handle root to make shooting unpleasant.
Another treatment of cold blue tomorrow and all should be well I think.
