Good advice. Since you're just getting started with that smokepole, I'd have a little notebook to keep track of the number of rounds, amount of powder, patch thickness, ball size, and if you can record it - temperature. Hot days and cold days can affect performance - not much you can really do, but it helps to know so when you look back to compare how things were working, one set up versus another, you have all the relative facts for consideration.
Be advised that you will slowly build up a pantina in the barrel as you shoot more and more balls - this is a good thing, so don't use the wire brush like on modern rifles. After you've put about 100 rounds down the barrel, go back to bench and check her out again. Things may have changes as the barrel got a little tighter.
But be warned - as old codger at club told us - if you're not shooting good and bench check the rifle - it the rifle is okay, then you KNOW you're the problem, before you only suspected it . . .
Have fun with it and enjoy shooting!
