My personal experience is that most of the claims for various products that they will "season' your barrel are, for the most part, bunkum. When someone speaks of a seasoned barrel, he usually means that it is more resistant to fouling and corrosion. You can get your barrel to this condition two ways (that I know of, anyway). First, you can shoot your gun a lot keeping the bore extremely clean after each range session and well oiled with one of the really good products such as CLP. After you have shot your gun a lot, the bore will become polished from wear. This polishing will smooth and minimize the surface area for fouling and corrosion to occur. You can speed this process up by polishing your bore using two to three grades of valve grinding compound. Put a little of the coarse grade and a couple drops of oil on a tight fitting patch, using a rod with a muzzle protector (extremely important) and give the bore about 25 strokes. Add a little more grinding compound and oil and give it 25 more strokes. Do this until you have given the bore 100 strokes. Then use a fresh tight fitting patch and repeat the procedure using the medium grit. Finish up by repeating using the fine grit for a final polishing. Now thoroughly clean all of the grit from your barrel, oil it up and it should now be "seasoned" :thumbsup:
I don't know if this is the only way nor if it is the absolutely best way but it is what works for me and has done so for the nearly 40 years that I have been building and shooting muzzleloaders. Just remember, my advice is absolutley free and it's worth every dang penny of it. :haha: :hatsoff:
