Well, I'me a Ruger #1 freak so I have 20 of them ranging from .22 Hornet to .416 Rigby. I also have one Browning B-78, now discontinued.
If you really like a .270, I'd look for a #1B with 26" barrel for the highest possible velocity or the #1A with normal 22" barrel, whichever floats your boat.
I have the #1A in .270 and have been kicking myself for passing up a "B" model in .270. Oh well.
Basic thing to look at is Rugers with a red recoil pad mostly have contract barrels some of which were not good at all. The Rugers with black pads have barrels made by Ruger and are considered good. With that said, there are many tricks to make a #1 shoot good. I've only had one Ruger, a #1A that had a really bad barrel. After determining the problem, I sent it with documentation back to Ruger and it came back with a brand new barrel. FWIW, that 7x57 #1 is my all time favorite of all my #1's.
With some luck you might find one for around $600 at a gun show, especially if the wood looks a bit hard. I bought a 25-06 "B" model for $400 that looked like it was rode hard and put away wet to use as a donor. Damn thing shot .25" groups all day long.
Later I found another 25-06 with superb wood and looked like new. So far 2" is about the best it will do. Both guns are red pads.
BTW, I forget which distance but Ruger's accuracy is two inches at with 50 or 100 yards. Most of mine will do much better than that.
and before you ask, yes, I do hunt with those rifles.
