welcome to the world of Winchester primers. I was using Winchester large rifle primers and have had the same results I measured the primer and it was 1/2 a thousand smaller than cci or federal so changed primers

If the Winchester primers are too small? What about their ammo they use the same primers.

Over the past 50 years, I have experienced this type of primer failure at least once with every make of primer available, including RWS and Norma.

It is not a nice thing to have occur, since some bolt face damage is inevitable. However, with manufacturing techniques used, a weak walled primer is certain to get out there, sooner or later.

Contact Winchester about it, but don't expect the world will stop turning, lol.

FWIW, both Winchester an Remington LR primers are ever so slightly smaller in diameter than are RWS, CCI and Federal.
