We are normally best served using the correct primers for the correct purpose (SP with pistols and SR with rifles) unless there is a COMPELLING reason to change.

As a for instance, it is RECOMMENDED to use small rifle primers in the .45 Casull (I think they would have been better to have stayed with Large Pistol primers but that is another story entirely). The pressure that the factory Casull's operate at require thick, hard cups to avoid cup flow at the firing pin indentation (which, at best, could tie up the revolver).

Small pistol primers have been recommended by some in the .22 Hornet. Accuracy may be better in that very small rifle case and normal pressures do not exceed small pistol specifications. Small pistol primers are used with the .357 Magnum and it can operate over 40,000 psi which is the same pressure level as the Hornet.

I try to use the correct primers for the job.

Regardless which primer you use you MUST work up the load again if you change primers in full loads - otherwise you could easily get into trouble.

FWIW
