Midway has barrels in 35 Whelen for the Savage rifles. You can change it yoursel, so they claim.
They did have them but unfortunately the Adams & Bennett barrels for the Savage 110 have been discontinued. They were fairly simple to change, provided you had a barrel vise, a Savage barrel nut wrench and a set of Go- No Go gauges. A good set of biceps didn't hurt either.
I see where they stil have a few left and they are on closeout at a good price.
