And for twenty years I have been abusing, forcing and crushing CCI primers into .38, .357, 9mm, .45ACP, .30-30 and .30-06. And none have gone bang at the wrong time. I will admit that they do fit a little tighter then the Winchester primers. But I do fear a primer that falls out in a magazine or a cylinder so I tend to use the tighter fitting CCI where a hot load is not needed (Winchester primers seem to give about 30 to 50 faster fps. And makes for a fine adjustment to performance.
At this point I wish to make a small disclaimer: "One of the reasons that there so many manufacturers of many products is if you don't like Post Toasties, you can buy Kellogg's corn flakes". Don't like one manufacturer, try another. A free country and I helped to make it that way.........Damn...It's raining out there and I have to shoe a horse today....
