In today's world, I say get the rifle and action brand you want, the stock you want, and finally do the barrel you want thru a custom gunsmith.
If you have an action you already like, the barrel is a lot cheaper than a new rifle.
From ER Shaw to Pac Nor, to Douglas, they will all give you more than a field hunting rifle barrel at decent prices...
if you want benchrest accuracy, there are those out there also..
The 6.5 x 55 is just an inherently accurate cartridge..it is worth it getting the barrel length you want, the contour you desire... just the same as picking the scope you want...
