Book's on the way. I got the swamped barrel and the late ketland lock. I'll look for a shoot in the area. This is all terrific advice, thanks again.
The swamped barrel makes it nicer to carry, and resembles the contours of forged iron barrels. The Late Ketland lock dates it by the lock (I don't know the dates offhand) but most importantly gives it credence as a Southern-styled gun. The "standard" Siler is a Germanic lock and such were not normally used anywhere in the South BITD.
They (Siler/Germanic locks) are heavily used however by entry level kits and by some gun makers, even on "Southern" guns. Kudos on getting the right lock.
Here's another tidbit: Clean with water (consider tow and worm in the place of patches/jag). Not hot water, not warm water-just water. Water is the perfect solvent for black powder residue and using anything else often leads to issues. Heated water often results in flash rusting-which fails to occur with cold water.
Avoid any substitute powders, they vary in formulations, and some are very very bad for barrel steel. It's far too easy to order BP (of various mfg's and granulations) to suffer a rotted barrel from "convenience" (or ignorance or faith in a mfg's spuriuos marketing claims). It's important that a new guy learns this up front because once a substitute has started etching the bore, it's very difficult to get it stopped.
NOTE: as with everything complicated in life, there will be those who argue the other side, citing their long history with one thing or the other. That's great, but the chemistry and metallurgy underlying the root of barrel pitting by perchlorated powders is sound. They also give off cyanide in the smoke.
Speaking of complications. There are many dozens of threads with hundreds of replies-and probably as many recipes for patch lube here on this site alone. You'll have to work that out for yourself when you start working up a load. Don't just pick a load and shoot that forever. Start with a load and shoot rested groups to determine how accurate that load is, but until you work out a patch thickness/ball size combination that works (with no blown patches and no build-up), all accuracy testing is irrelevant. You can go ahead and pick a load to start shooting, just so you can work out all the various details and get familiar with the process and all.
Last thing you do is adjust the sights-after plenty of shooting and working out your combination. This can save you from having to replace a sight that was over-filed in the beginning.
There's pretty much nothing you can ask that hasn't been asked, so don't be surprised when folks say "do a search" if you inquire about some hammered out topics (especially when the anvil is yet ringing from the last "go around"). You'll see.
Black Powder TV-Bob has lots of good info up.
Welcome, and best of luck and don't complicate things more than they have to be. I'd load and prime with 3F in the pursuit of simplicity.
PS: When you get a flash in the pan.
WAIT!!! WAIT!!! WAIT!!! The gun could hang-fire and the delay could be a fraction of a second, or much longer. Just wait
a few seconds to several before recharging or investigating, because there may be a slow spark working and having the gun pointed the wrong way when a delayed charge goes off can change your life.
I've seen "gun familiar" folks not do this and it freaks me out every time. It's horribly unsafe.
