Here's my Ruger MK II 77 with a Hart barrel in #1 contour at 25.5" long in 270 Winchester. It is my first rifle I bought at age 21. I get 1/2" groups with it with just about any bullet I choose with some work.
That said, now that I've had many custom rifles built, I won't do another Ruger because of the action. It is simply a bit more difficult to work with but can be done. You can get the factory trigger reduced or get a rifle basix and you can get aftermarket stocks for them. I do NOT like the angle of the action screw.
My rifles of preference are trued 700 actions, custom actions, or Sako. My preference and arguably the preference of just about all builders.
That said, a factory Ruger is a great work-horse of a gun and reliable on feeding/extraction and unless you make a habit of shooting beyond 250 yards the Ruger will do anything any custom will do and I'd put my Ruger 270 against anyone else's rifle on medium sized game inside of 600 yards. I'm shooting 130 TSX over Re19.
When in Texas, I shot it at 500 and got a 4.5" group once and a 6" group once with 4 shots each. That accuracy comes from me, a fat, pot-bellied guy who breathes heavy and laying prone. The action was trued by a smith I used to work with in Tucson, AZ at the shop formerly known as Jensen's Custom Ammunition.
