I have used bore butter, neatsfoot oil, tender flake pig lard, vegetable lard, and a host of other barrel lubricants. Can not see any difference in any of them except for neatsfoot oil and sweet oil. Have not found a difference in the accuracy no mater what is used as a bore lubricant, sealer. Except f for the fact that neatsfoot oil is not as messy as the others I have used. I also swab and clean my bore between every shot with Butches black powder bore shine. As for (seasoning the bore) that's a bunch of poppycock. The steel used in today's modern rock locks and cap locks is far superior to anything used in the 18th and 19th centuries. A frying pan is cast iron not ordnance grade steel and ordnance grade steel can not be seasoned with anything it is too hard and non porous. Just lube your bullets with what ever non petroleum based grease you happen to have around the house, just be sure there is no salt in the lube and yur good to go. You can even use sweet oil (18th century name for Olive Oil). One more thing always clean your barrel after shooting with warm soapy water. I like to dry my bore and then soak with WipOut for 24 hours, then patch out again. WipeOut will remove any carbon fouling left from the warm soap and water treatment. I read the patch if it is clean I am good to go and the cleaning is finished, if the patch shows any fouling at all I do the WipeOut treatment for another 24 hours. WipeOut also has the advantage of being a rust inhibitor for storage. Everybody and their dog has a different method off greasing their patches and cleaning their barrels, use what ever works for U as there is no absolute written in stone right way to do it.
