I am in the process of reloading a batch of 223. I just realized that I am out of SRP, but I have lots of small pistol primers, both regular and magnum. Is anyone aware if it is safe to use SPP in rifle cases designed for SRP?
Small pistol primers in small rifle

Nope. Stop. Do not pass go.
You can get away with working up a pistol load with small rifle primers, but the pressures are too high to do the reverse.
About the only rifle case that you MIGHT get away with it would bbe .22 Hornet.

I did the same one time with 260 loads. I put pistol primers in them. Pulled all the bullets, saved the powder, replaced all the primers and started over. The pistol primers have thinner jackets, and won't likely handle the pressure of a rifle load. A little more time spent, re-priming is better than a failure in you face.
All depends how attached you are to your eyes and other assorted body parts...
You might get away with it. You might even be able to find people who have done it without issue. I personally wouldn't try it by remote control from the next county.
Second Thought. Small rifle primers are about 5/1,000" deeper than small pistol primers, which means that the primer pocket should be correspondingly deeper. Depending on your rifle, you might get inconsistent results with the shallower pistol primers in rifle brass.

VICKERS HARDNESS TESTING OF SELECTED PRIMERS
Frederic Tulleners, California Department of Justice, Erik Randich, Lawrence Livermore National Laboratory, and Mike Giusto, California Department of Justice
A study was conducted to evaluate the Vickers microhardness of primers from five different brands of 40 S&W unfired cartridges from major manufacturers. Primer hardness is affected by the structure and the composition of the brass used in its manufacture and by the nickel plating if one is used. This study measured the Vickers microhardness and the thickness of the primers. Nickel platings increased the apparent microhardness of the primers. Differences were found in the average microhardness values of the underlying brass of the primers, and these differences were clearly attributable to the different grain sizes of the brass.
