there are all sorts of mix and match going on with regards to primers.
Do some basic research on the specific dimensions of primers, calibers, and loads, and if you aren't comfortable with your findings don't do it. it's as simple as that.
I've mixed and matched stuff over the years. example- 22 hornet there are many people who find that they get better accuracy out of small pistol primers than they do out of small rifle primers. Winchester large pistol primers are only one version, says on the box you can use them for standard or magnum loads. If I'm making something that specifically calls for a magnum primer, I tend to try to use a specific magnum primer vs a winchester (for example, H110 really needs a magnum primer, so on my H110 loads I tend to use a CCI magnum LPP instead of the winchester LPP primer even though it says I can).
if you are shooing a caliber that's high pressure (357 sig), or very small tolerances for error (5.7), I would err on the side of sticking to published resources. If you haven't been doing it long enough or know how to read pressure signs, stick with known data.
