Uh oh...

I was at P&D back on Friday afternoon getting some more reloading components, and one of the items on my list was small pistol primers (for my .38.) Being completely wiped out from a double shift, I never bothered to check the bag contents before I left, silly me. The thing is, I know I specifically said SMALL PISTOL. The girl helping me out might have gotten confused (it was the young, cute one) because when asked brand preference for my primers, I said CCI. All they had in small pistol was Winchester

I finally got around to sorting out my purchases to go onto my shelf that I keep most of my reloading supplies in, and lo and behold, I have CCI small pistol MAGNUM primers. Not Winchester small pistol. Now, everything I've read clearly says using a magnum primer in a non-magnum application is bad juju.

Think it'll make much difference if I swap them in on a starting load of Universal (3.5grs, according to the data I have here) and letting it ride? Think I'll be able to exchange them over at P&D? Anyone have 3 boxes of Small Pistol primers they'd like to trade straight across for?

Since you are going to be loading them in I assume 38 special loading. The magnum primers really should not affect things too much. Generally Magnum primers provide for a longer burn to ignite slower harder to ignite powders (Think H110, 296, etc). Since you are igniting clays, I wouldn't worry too much about using magnum primers in your loads. You may experience a different group size but overall I doubt that you would have any problem substituting the magnums into your 38 special loads. The only thing I would be leery of is that CCI primers tend to be some of the hardest primers out there. If you've had any kind of trigger work done, you may have a harder time igniting them. My 610 HAS to use Federal primers otherwise it becomes unreliable even with Winchesters. I doubt it would ignite CCI's at all. If you have a factory set trigger/hammer spring, it should ignite them just fine. I'd load up say 25-50 and see if you notice any difference. I doubt you will with such a lightly loaded cartridge/powder combination.

I wouldn't sweat it
