The term "seasoning a barrel" came from Thompson Center during the early 1970's. It was used in advertisements that were trying to sell Thompson Center's patch lube "Bore Butter".
I think they jumped on the term because the patch lube has butter in the name and (for those who don't know) the stuff is yellow, like butter.
The ad's did a lot of talk about the Bore Butter soaking into the pores of the steel just like butter does with a cast iron skillet, even though they should have known that wrought steel bar's don't have the open grain structure that cast iron has so the whole idea is silly. The ad's urged shooters to liberally coat their bores with their Bore Butter after cleaning their guns to season and protect them. (Uses a lot more of their product than just using it as a patch lube.)
Oddly, Thompson Center's Bore Butter does a rather poor job of protecting a freshly cleaned bore and it does nothing at all to "season" it.
