Magnum wheel man I checked a case I picked up of .223 Hornady Steel Cased Match looked in with a flash light. It is boxer primed. Good to know that it will not break a decapping pin if I miss it. Though I police my range pick up rifle brass with a magnet. It did stick to the magnet.
Ok now as far as 9mm Luger goes. If you can pick it up enough times it will eventualy split at the case mouth.
30-06 Paper clip test to make sure there is no cut ring inside the case. Check trim length. If you are shooting a semi auto it is a wise practice to shoot 5 times. Then scrap. If bolt action then load till the primer pocket gets loose, or the case mouth cracks.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
