Mongols of 13th century had no wootz ( bulat)
Nobody, EVER made barrels of firearms from wootz.
Anosov's bulat process did not depend on quenching. He did not increase hardness of bulat: all "bulats" ( wootz) have Rockwell C hardness in the range between 20 and 35.

Salaams Ariel, I am late in answering since it has taken me a while to try to discover the Barrel Making techniques particularly in Persian gun making...but in fact these are virtually unrecorded. I note the following which is interesting as it supports the almost unknown nature of this technique ... from ...
http://www.iranicaonline.org/article...on-and-muskets
Quote" Despite the availability of a technical text such as this, the chancellor of Shah Solṭān Ḥosayn (1105-35 /1694-1722) sent a letter to Louis XIV of France requesting several makers of cannons and other firearms (Qāʾem-maqāmī, p. 114). During the reign of Nāder Shah (1148-60/1736-47), material and craftsman for gun-making were also summoned to Marv in preparation for a campaign in Central Asia (Marvī, pp. 911-12),
but no technical information about this is available.
In the Qajar period new techniques of cannon making were introduced from Europe by Prince ʿAbbās Mīrzā. The core mold was no longer employed, and the cannon barrel was bored with a boring mill constructed according to European models. The improvement in technical performance was remarkable. If a cannon during Nāder Shah’s campaign against the Afghans needed 20 to 30 persons to be loaded and fired and 100 to be carried, the new ones needed only 4 to 5 persons and 4 horses (Donbolī, pp. 133-34).
In this period some books on artillery were translated from European languages into Persian (Afšār, pp. 90-91), but they contained little or no information about cannon making (e.g., Māzandarānī).
Musket making. The best description of musket-making is found in the travel account of Jean Chardin (q.v.), who visited Persia in the second half of the 17th century. Persian muskets, according to him, were all match-locks (Chardin III, p. 558), as at the end of the 16th century when 300 musketeers from Isfahan ignited their matches before attacking the Uzbeks (Eskandar Beg, p. 466). According to Chardin,
the barrels of these muskets were heavy, thick, and damascened." Unquote.
Perhaps, therefor, it is not a matter of these barrels never existing but more associated with the fact that no record was ever allowed / made recording the secretive method... It does seem however that in some cases where damascening took place on hand held guns that this was as a decorative technique rather than actual gun barrel manufacture.
The following is noted from
http://firearmshistory.blogspot.com/...welded-or.html
Quote"... wootz steel (the steel used in the so-called "damascus blades") was NOT used to make damascus barrels
very much.
William Greener in his Gunnery in 1858: Being a Treatise on Rifles, Cannon and Sporting Arms writes that these barrels are rare and on examination of the available barrels made by wootz steel workers, most were actually were made of commonest iron with a very thin plate of wootz steel around them, indicating that the wootz steel ore was becoming very valuable, since the mine in India where the ore came from was running out. Instead of using wootz steel, the more common option was to use pattern welded steel and the reason that they were called damascus barrels is because the patterns on the pattern welded steel resembled that made from wootz steel. So the name "damascus" is a misnomer and when we say "damascus barrels", we really mean "pattern welded barrels". In pattern welding, two or more metals are used to make the barrel (usually iron and steel bars, or steel bars of varying carbon content)."Unquote.
I therefor suggest that before this period of dwindling supplies of Wootz ore...that Cannon Barrels may have been attempted and that the technique was lost but that the secondary reason ...that of the time problem...when the raw ingredients ran out may be masking the fact that wootz may have been used in Barrel Making previously...but we just cannot see it.
