Navy Six

Is there any connection to Dillon presses? It seems both reported issues were used with Dillon. I recently had an issue with Winchester large pistol primers seated in 38-40 cases at a SASS event. About 50% of my rounds failed to go off in my rifle. Never had this happen before. Took the remaining rounds home, dismantled them and re-seated with a RCBS hand primer. All 24 rounds went off as normal in that same rifle. I always check every round I produce and all primers were seated below flush of the case rim. However, the hand tool actually seated these primers deeper. That's when they all went off. This is not a knock at Dillon--my 550B has given 40 years of service but lately the "feel" of seating only large primers has begun seem different.

I've lately decided to come up with some type of solution too. Hopefully something simple and easy to remove.
