A while back, a year or so ago, either RIFLE or HANDLOADER had an article on the 270 Winchester. Specifically the performance of the 270 Win in a#1 with a 26" barrel and today's modern powders versus the industry standard 22" barrel.
They were very impressed and were able to achieve "Light Magnum" velocities with the added 4" of barrel and really liked it. With 130s they were giving the 270 WBY a run for it's money. Stands to reason that the 270 Win, on the 30-06 case is a BIT overbore when necked down and therefore would benefit from the longer barrel and slower powders, especially with heavy for caliber bullets. Also that being less overbore than the 270 WBY it would shine with the 130.
The 270 Winchester is "common" within the #1 production. Other than as a non prefix rifle as previously noted.
Just wait and watch. They DO turn up at a fair or better price. At least half of the "Donor" rifles I've used for projects over the last 35+ years started life as a 270 Winchester #1 in some configuration, including RSI, "A" and "B"s.
The only one I've kept intact as a 270 Win is a non prefix "B". Don't get me wrong there is nothing wrong with a 270 Win and a lot to like BUT I have other cartridges I prefer to hunt with.
