[OLDMAN]

Yea, I know this is a goofy question. But, I want to fireform my PJ/Oldman 7-30 waters and there is not one gun shop open today and I do not have large rifle primers on hand. Can I fireform the 7-30 using large pistol magnum primers.

Can you? Yeah probably. BUT I wouldn't.

If you make sure you use a load that is below the pressure threshold of the LP primers tho it shouldn't hurt anything. Get above it and you'll perhaps blow some primers. So keep it to 40,000 or below.
