Cayugad described it very well. I have the brassy sister rifle to yours (Shenandoah) and you very rarely want to take those pins out to keep "intact accuracy". You will also want to consider buying FFF or pistol powder AND a hotter nipple like Red Hot/Splitfire for that rifle. If not, then you are risking occasional hangfires. I own a few Traditions sidelocks.. believe me I know the manufacturer pretty darn good.
Also! Since you won't be removing the stock & you don't want nipple-area fouling to seep in between your stock & barrel, you must grease where the barrel meets that stock edge. Do the entire length of the barrel. I use round metal-cannistered Mink Oil.. found where all the shoe polish is at your neighborhood Wally World. Fill the two grooves (one on each side)... then wipe off & stroke it back & forth a few times like you're polishing it.
Also-again! Depending on your powder, charge & lead bullet softness, products like Dawn detergent & T/C-13 won't remove lead. Buy a solvent that will. Just because the solvent says it's good for blackpowder/muzzleloader weapons, it doesn't mean it cleans properly. You may have to venture over to the centerfire/shotgun/rimfire aisle in that hunting section to find solvents that remove lead.
Also-again-again! The open sights on the Kentucky, Shenandoah & Pennsylvania suck royally.. too 1860ish primitive for my current 2004 tastes.
