45-70 Gov hand load max pressure

I've been considering hand loading some 45-70 ammo but I don't know what the max pressure tolerance is for my rifle. Lyman load data indicates minimal loads for the old trap-door Springfields. Loads are a little hotter for Marlin and Winchester lever guns. Loads are hottest for the Ruger No.1 but Layman explicitly says not to use those loads in any rifle other than Ruger No.1 and No.3

I shoot the NEF / H&R 45-70 Buffalo Classic and I can't seem to find any information on what kind of pressure this rifle can take. Any suggestion?

The 45-70 BC, is built on the SB2 frame, same as the H-R 500; most trapdoor loads are listed as 28,000 cup. The 500 is built to withstand 50,000 cup. I mostly use the marlin loadings in my 45-70.

Go over to graybeards web site, those guys live and breathe handi rifles. Check out the FAQ links, got alot of useful info.
