What are you trying to say? Any of the custom barrel makers who deal in the TC lines will chamber you a barrel in 240 WBY if you so choose.
I hope you are right. If so, it's news to me. I look at custom Encore barrels sometimes and I don't recall ever seeing one in a Weatherby calibers. I guess I thought the reamers weren't for sale. Like 6.5 Grendel or the Laz cartridges?
