i never heard of seasoning a bore untill i joined here. Ive never done it in muzzleloaders or centerfires and never had any problems. When i buy a new ml'er i just take them apart and make sure theres no flaws and then start with a small load and shoot untill im on paper and then start working on hunting loads. i really wouldnt even worry about seasoning your barrel unless you can see by the naked eye that its rough inside.
