Only thirty-five years of muzzleloading?? Why, son, you're just a pup. :grin: I've been at this for over 40 years. :haha:
I, too, recommend WD-40 over the alcohol for removing residual water from your bore. :v Although, I must admit that I have used denatured alcohol for this purpose. It works but as you say, it can damage your stock and WD-40 is cheaper in the long run. Where we differ is that ever since I cleaned my first muzzleloader back in the late 60s, I have been rinsing with boiling water. As soon as the water has drained out, I follow with a couple dry patches and then a really good spray of WD-40. after the WD-40, I run a few patches throgh the bore to remove any of the WD-40 and then a patch with a good rust preventing oil. I have used several different things in my bore to protect it and all seem to work just fine. I used to use 3 in 1 oil, then I switched to Baricade. Now, I am using CLP. All work fine and no rust problems. I would not use any natural product such as bear fat, olive oil, Bore Butter, etc. because they are oils but have no rust inhibitors in them. I've never had a rust problem. I still have that first muzzleloader and it looks as good as the day I brought it home from the gun show.
My first rifle was a T/C Hawken with a removable barrel. I do not use the boiling water treatment on longrifles, though. For them, I simply rinse by pouring clean water down the bore, placing my finger over the muzzle and tipping the gun up and down several times. I do this a couple times and then run dry patches through a couple times followed by the WD-40 and a few dry patches followed by the oil patch.
I wipe all of my stocks down with soapy water and then wipe them with clear water. When everything is nice and cean and dry, I wipe the barrel and stock down with a light coat of Renaissance wax and buff them with a soft cloth. Except for a little light wear and a few inevidable small dings, they are all like new. :thumbsup:
These are just the musings of an old fart so take them for what they are worth. :idunno: :haha:
