Depending on where you live, your best bet on finding out
all about shooting a Colt revolving rifle would be
1) a reenactment or rendevous
2)local state or National historical parks
3)gun dealers and/or gun shows
4)National Muzzle Loading Rifle Association see their web site
5)Library books and videos

Once you find the right person they will be more that willing to help.
Good Luck
