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?

I shoot the leverevolutions in my handi. I havent ran any across the chrony but I think they run about 1800 fps. I had the same problem as you I couldnt find anything about how much these guns can take. I am planning to reload some of the flextip bullets to about 1800 fps because I know my gun will handle this. The load data for the flex tip bullets has loads up to 2100 fps I think. I dont think I will go over 1800 unless I find out it is safe.
