I just learned about a problem with WW primers from 2014 and 2015 in which the primer cup failed and allowed gas to pit the bolt face or slide face.
A word of caution if you have WW primers or reloads from that time. Winchester never recalled the primers apparently but folks on the internet mentioned complaining to Winchester about the damage and they paid to have the firearm repaired. A fellow on another forum showed a picture of his M1A bolt with bolt face pitting from a failed WW primer of that vintage.
