Hi, tunes....
There's no hard and fast answer to your question but as a general rule you'll find an awful lot of good 1150 to 1200 fps loads that are under 7,000 psi, which is a pressure most of us feel is safe for a vintage gun in good conditon. For load information check out the Hogdon and IMR reloading sites. Should you find a load for Federal plastic that is attractive you can use that data in a paper hull and be quite safe. However, never take paper data and put it into a plastic hull.
PM me if you'd like to have my favorite Federal loads for my damascus guns.
