I've seen brand new stocks break into multiple pieces at my local club. Well, brand new stock, singular, anyway. No injuries, but, a messy sight to behold.
Wood is wood. It breaks, sometimes in areas that you would never believe it could. If you could see the repair from 6 ft. that might be a better heads up to go cautiously then a complete surprise on an un-broken and seemingly perfect stock.

Best,
Ted
