Can you use magnum primers when reloading 9 mm? I ran out of standards but still have a lot of magnums. BTW, I'm using a 115gr fmj with 4gr of Bullseye. Any suggestions?

Yes you can. As said, just start low and work up.
I've been doing it for years; decades before there were any "panic" buying shortages.
I suppose if you were on the ragged edge of a cylinder/chamber bursting load a magnum primer might push you over into the danger zone so to speak. But for "normal" loads do as advised: start low; work up ... same as always.
The only "danger" I foresee is some magnum primer cups are proported to be harder than non magnum. Couple a weak hammer or firing pin spring with a hard cup and you might have ignition problems.
