i like the blackhorn 209 in my 45/90 and 45/110 sharps dt's
777 works fine to... both are much perfered over standard bp..
#1 reason is a breeze to clean. but all shoot with same accuracy
with there givin load charges.
i have not used pyrodex in the sharps, but i have used it with very good results
in my .50 ss huntsman along with the others you mentioned.
all of them will make you smile... when you touch the trigger !!!!
