Another of the old-time pieces of misinformation is the practice of using Bore Butter to "season" the barrel of a muzzleloading firearm. Now Bore Butter is a reasonably decent patch lubricant, but then almost any somewhat slick oil-based lubricant is a reasonably decent patch lubricant. Even spit is a good patch lubricant. The old Timers that have successfully used Bore Butter as a bore preservative have removed the mix of crusty fouling and burnt lubricants that are often misidentified as seasoning, so the bore is clean before treating the barrel with Bore Butter. The Bore Butter will dry out in the barrel and depending on how well the cleaning has removed all the corrosive fouling that could get trapped under the layer of Bore Butter can protect the barrel until all that dried on lubricant is removed before taking the gun out to shoot.
@ElkStalker, good job on bringing that T/C Hawken back to shooting condition.
