....seeing a graph of the pressure in a barrel upon discharge? I am speaking of a graph for black powder.

Not certain why I want to see this again (if I ever saw it before.) but as I am beginning to load this 45-70 BPCR round, it seems as though at least a casual understanding of barrel pressure is important.

I am not so concerned about barrel failure. I am loading light at 50 grains for now. I just want to know about pressure in the barrel for this big round.
