so i am at the farm last night and a friend calls me,,he and a friend have been loading 45acp using a midrange of power pistol he says and he realized that they had loaded 800 rounds using small rifle CCI rifle primers. not magnum but standard small rifle. i dont know the actual power pistol load they were loading but he stated it was not max but midrange. what would you tiell him to do?
I've read the only difference in small rifle and small pistol primers is the force required to set them off. Small rifle requires a harder firing pin strike than small pistol. So they might get some failures to fire if the firing pin in their handgun is weak.
My buddy who just got his k-Hornet barrel for his encore and is starting to load for it says a lot of hornet shooters load with pistol primers for accuracy because they say the small rifle will actually get the bullet moving before the load fires in such a small case. He is not sure if it's true but he's heard it from enough he is going to try it.
But the 45 ACP is pretty low pressure compared to other pistol rounds even with stiff loads. The difference if any shouldn't even be noticeable much less dangerous.
I guess it was at least 25 years ago while loading for my Hornet I noticed that I was loading with small pistol primers. I had loaded 50 rounds. Before I used them for hunting I grabbed my Chrony and went to the bench, set up the targets and popped off 3 rounds. Same everything as if I had been using small rifle primers.
Shoot them.
