I recently built a 35 Whelen Browning A-bolt from a unfired new A-bolt in 30-06 that I made a classic stock for w/shadowline cheekpiece from exhibition grade claro walnut and I used the best Douglas has to offer blank, ans fitted/threaded/chambered/turned down myself. It groups around 3/4" for 5 shots at 200 yards. So rebarreling is a worthwhile reasonable cost option.
