The distance from the lands will be different for each rifle.
I have a H&R Buffalo Classic and the leade is very short, most flat point bullets that I've shot in that rifle seat right at the crimp groove, and seated to that length have very minimal distance to the rifleing,0.020" or less. The 1885 Browning highwall will probably do better with bullet weights in the 500-530 gr class.
Both rifles should perform best with the cast bullet close to or touching the lands, especially if you're shooting black powder.
Your on your own if your shooting jacketed bullets or cast bullets with smokless powder!
