Seriously now, if I wanted a .35 Whelen (even though I'd far prefer a .338-06) I'd be going to gun shows and used gun shops looking for a donor rifle.....a Remington ADL (or classic) .30-06, a Winchester M-70 30-06....etc something I was comfortable with and build one.

Even a cheap 8MM mauser 98 will do the job nicely but I'd prefer a modern action.

A FTC barrel from douglas is about $260 and installation and bluing is about $100....the FTC is already threaded and chambered.....

I'd far rather take this route than buy a new rifle.
