MagTech is Brazilian and I believe the US imports are SAAMI spec. Anyway, it is brass cased and Boxer primed. I don't care for Wolf ammunition. Steel cased ammo works fine, but as a reloader I'm always looking for reloadable cases.
Look for the plain box Winchester or Remington/UMC plain box. Should run about $10 per 50, I've seen Magtech and Fiochi for as little as $8.50 per 50. Will all work, and work well.
