I will assume you are talking 45-70...
I have shot a lot at 49gr. Chrono between 1,875 and 1,925 depending on barrel length (I have both short and long barreled Henry rifles).
Great deer load...their BP drops very fast with a shot through the heart/lung area.
42gr was actually more accurate in my short rifle with velocity at 1,575.
These were with Starline brass and Tula magnum primers (I used magnum because I have so many...also the 42gr load is low density...).
