I'd stick with your first shot procedure, if you need a quick follow up, charge, ram home a power belt, and adjust for what you expect it to do.
That is what I'd do if you plan to not mess with it. First shot is the one that counts anyhow. If a subsequent shot is needed, just make sure to remember you need to adjust accordingly.
And fwiw, many folks have 1st shot (clean bore) flyer issues. It is more prevalent with BH209, than pyrodex or T7 from what I've seen.
