Were it my rifle, I would carefully examine the bolt face and lugs. Any cracks or distortion is cause for replacement. I would mic the end of the bolt. If the bolt body is smaller than the end, replace. I would also run some go-no-go gauges into the chamber. If it's new bolt time, or if the no-go fits, unless you know what you're doing, it's time for a good gunsmith to give it a thorough check over. In the case of my Whoops, My bolt face was a little messed up and the extractor was wrecked. It cost me the price of two bolts off ebay and the time to borrow the right go-no-go gauges from a friend.
