A few years ago, I had exactly the same problem with Remington UMC 9mm, in the green and white boxes.

I would fire them in a Ruger convertible and get the pierced primers.

A whole litany of ammunition from other company's failed to have a single repeat episode.

This caused me to eliminate the pistol from the equation.

Out of perhaps 100 rounds, I had the primers pierce on perhaps 10 cartridges.

With this, I stopped using this ammunition.
