Anyone who has read my posts knows I am not a believer in "seasoning" bores (as opposed to shooting a barrel in). A bore so seasoned would eventually have the rifling buried not to mention a shrinking bore dia. Such seasoning cannot contribute anything to a barrel even assuming it is possible. Prbs don't stick in the bore. So what problem is this mythical procedure supposed to solve? I even reject the notion that "seasoning" - as in the seasoned surface of a (cast iron, not wrought iron) frying pan. If those early rifles did, in fact, develop a crust in the bore, it was probably mostly rust and is the reason for "freshening" them periodically.
Back in the old days a factual understanding of science and metallurgy was not as wide spread as it is today. Some modern ML aficionados cling to various myths and even use "non words" in their speech because most likely these myths and verbal affectations sound "old timey" and wise. As an example such as using corncobs for personal hygiene rather than bathroom tissue are, of course, not only unnecessary for experiencing a small part of history but downright silly.
It's a shame that a few purported authorities/experts, who may have blogs, videos, etc, will espouse products and procedures that will dim their otherwise well deserved reputations. Frying pans aren't gun barrels and never were.
