Just purchased an EMP Ronin 4 9mm. Went to the range and the ammo is used NewTuran brass FMJ 115gr. There were flecks of brass all in the chamber and fouled the firing pin. Took a bit for the Range Armorer to clear and clean. The book says high quality ammo, no reloads, or remans...What brand is recommended by Springfield to shoot through this weapon?
