They didn't have steel barrels 200 years ago.
But they did by the mid-1830's - drilled through cast steel barrels (a type of steel and not that the barrels were cast to size/shape). Wesson was using them by 1836 and advertised them as superior to wrought iron barrels. By the 1840's Remington was using them as well.

The tightness of the molecular matrix of a piece of steel doesn't lend itself to the traditionally thought of "seasoning" a casting can have.
Steel does not have a molecular matrix - it is of a crystalline structure made up of various elements.
and yes back to the OP's original question:
"One evening a wolf came into camp as I was engaged in cleaning my rifle, one barrel of which was still serviceable, and a long hickory wiping stick in it at the time. As I was hidden by a tree, the wolf approached the fire within a few feet, and was soon tugging at an apishamore or saddle cloth of buffalo calfskin, which lay on the ground. Without dreaming the rifle would go off, I put a cap on the useless barrel, and, holding it across my knees in a line with the wolf, snap ph-iz-band went the charge of damp powder, much to my astonishment, igniting the stick which remained in the barrel , and driving it like a fiery comet against the ribs of the beast...
"George F. Ruxton, 1846, SE Colorado - his rifle was Westley-Richards 25 gauge (.58" caliber nominal) double barrel.
"La Bonte looked up from the lock of his rifle, which he was cleaning."
La Bonte's rifle was according to Ruxton a flint Hawken obtained in the mid-1820's -
"To effect this, he first of all visited the gun-store of Hawken (note: J & S Hawken), whose rifles are renowned in the mountains, and exchanged his own piece, which was of very small bore, for a regular mountain rifle. This was of very heavy metal, carrying about thirty-two balls to the pound (nominally a .54 caliber), stocked to the muzzle, and mounted with brass; its only ornament being a buffalo bull, looking exceedingly ferocious, which was not very artistically engraved upon the trap in the stock.
A further description of La Bonte's rifle -
"Each held a rifle across his knees, but””strange sight-in this country””one had its pan thrown open, which was rust-eaten and contained no priming; the other's hammer was without a flint."
