I don't have just one finish and most of what I do is restoration work in small amounts on any one rifle.
I do not use boiled linseed oil anymore for anything. I have gone to raw linseed oil or "Stand" oil which I think is the closest to the original "Boiled", today boiled has a bunch of chemicals in it for drying.
I guess it depends on how much of a hurry you are in as to the amount of drier you add.
Regardless of what mixture (the books are full of them) that you use get a pain of glass and put some on the glass then date it and see how long it takes to dry.
About every classic pre-war custom sporting rifle has a linseed finish of some sort or another. Each maker used a different recipe and contrary to popular belief they all dry.
