I have been reloading for over 20 years, and thought I had a rough idea of what I was doing. I went to get small pistol primers today (couldn't find any) and was told many reloaders use small rifle primers instead. Same goes with large rifle and large pistol. The rloading shop I went to told me there are only two sizes of primers, just labled different. I checked around and it is a common practice.

Anyone else heard or do this?
