Oops. I bought magnum SPP. Now what?

[Sniper 79]

Never a balls out load for me. I load for accuracy. Start low and when the groups tighten up I load the rest of what I have.

Not sure at what brass I have. Got a big bucket saved up of mixed once fired.

I bought a bunch of them a while back when the standard SPP were hard to find. I've been loading my standard 9mm plinking ammo with if for quite a while and never have had an issue. Like others have said, work the load up as normal and they'll be fine. Wasn't there a video somewhere that showed the different primers flame output a while back? If I recall, some standard primers put more of a flame out than some magnum primers depending on who made them and their QC.
