(This isn't "handload" or "reload" as such but I we don't think we have a Factory Ammo forum.)
Was testing a number of loads yesterday in my 8-3/8" 686-_ and I wanted to see where Hornady factory ammo shot on target compared to my handloads. This is Hornady .357Mag 158gr XTP. #90562. (~1250fps @ muzzle) (My loads run the same velocity between ~1250 and ~1300fps depending on powder.)
In two rounds out of the five the primer flowed back into the firing pin hole and locked up the action.
This 686 has 1,000s of very hot .357 rounds through it (IMHSA) and I've never had this happen with reloads, much less factory ammo. Will be contacting Hornady before I shoot anymore of this Lot.
Not the best picture but the center two you can see the raised impression where the outer two just have the firing pin dimple.
