Investarms or cabela’s hawken 45 cal fast twist barrel

[Albert Majerus]

I am interested in a Hawkin style percussion 45 caliber for sale on GB. It is listed as a fast twist 1:28, but I have researched the barrel for several days now and can find no evidence that a fast twist barrel in 1:28 was ever available in that Hawken style rifle.
Can anyone provide ANY info to indicate if that barrel was available in that weapon. Thanks Al

Good evening DB, I have an investarms .54cal and was curious if the TC barrels are interchangeable with them. If you have any info it would be appreciated. Thanks, Lloyd
