While at Sportsman's in Az this last weekend I needed some large rifle, large pistol and small pistol magnum primers. I got the large rifle primers OK, they were out of the small pistol mag primers and I screwed up and grabbed large pistol magnum instead of the regular large pistol. None of my reloading manuals show these primers for any of the cartridges I load for, .45 ACP and .44 Mag. What's a fellow to do? Do I eat the mistake and get the right ones? Or, can I use these for my cartridges???
