I started to reload a batch of 357 magnums today and then I noticed that in my Hornady 9th edition manual lists Winchester small pistol magnum (WSPM) primers for all their loads they've listed & then I go in my Speer #14 and it only lists magnum primers for some powders and not others.

I found two similar loads in both manuals using the same powder yet the Hornady manual states small pistol magnum and speer for the same load just uses standard primers. Again, in the Speer manual, some loads get the magnum primer and others don't meanwhile the Hornady book, all loads get the magnum primer...

I have a whole case of Winchester WSP primers, I'm just gonna use them... here's the load data I'm using today.

158 gr. LSWC HP

3.8 gr. TiteGroup

OAL 1.590"

I think in this case, I'm fine using standard primers.
