Say what you will. I had a supply of .45ACP brass that was imported, and featured deeper primer pockets that when loaded with LP primers would often not fire, no matter what gun they were shot through. I solved the issue by using large rifle primers, and never had any trouble. Most of those reloads were shot in a carbine that had a blow-back action, and the brass was usually beat pretty hard. A few 1911's also ate it up with no problems, and it was perfect ammo to take to classes and events where the brass was not easily recovered.
