So I'm sitting at my loading bench pondering on primer shortage looking at what stock I have. Not a lot of small rifle but 1 unopened 1000 small pistol magnums. And I got to wondering if a guy could substitute these in a 223 in a pinch? Anyone have any experience trying this? This is theoretical cause I still have a few rifle primers at this point but if shtf happens I'd like to know
 
Small pistol are exactly the same physical dimensions as small rifle, so they will fit.

Pressure is the issue. Some small rifle cartridges have historically used either, depending on powder and load. 22 Hornet and 22 Fireball are two cartridges that have historically used both.
 
I don't want to get rid of any of them, I load as much small pistol as I do small rifle. I was just curious if it had been done.... I heard a guy talking on jon pynches podcast about testing primers and he tried it in 6 dasher without incident
 
I did it once with a 204 R.
Apparently a box of Winchester small pistol got put into a SR box during a move.
I didn't notice it and loaded a box of 50 for the next day.
When I started putting things away that's when I saw that they were SPP.

It was too late in the evening to pull them apart and start over, so I figured I'd send one down range and give the thing a good inspection.

I remember reading an article on Accurate Shooter about primers and felt it would be safe to try it. I did measure the cup thickness, but can't remember if there was any difference in them.

Anyway, they shot fine without any loss of accuracy. I didn't run them over a chronograph since I had no reason to duplicate the loads.
