I'm glad now that I cleaned up my reply a bit last night, not much sleep these days. I just get my dandruff when TC gets an unfair bad rap when my experiences have been just the opposite. Improper maintenance will destroy most all rifles. I think the post really only made any sense if someone never cleaned a ML for several seasons and used any heavy bore product and simply tried to shoot it. I use Rem oil as a light final swab down the barrel of every rifle I own and have 0 problems with any issues. TC wonder lube has been a great product for the patches in the flintlock but it smells like ben-gay. Bore butter I'm sure works if used as instructed just like any other product. Use what works for you and as BB said hog-wash to everything else.
