I owned a .270 in Ruger 77 years ago. It was a long tang. It was just flat one of the best out-of- the box completely stock shooting guns I ever owned, even with factory ammo. I have also owned Rugers that needed some bedding work to make them acceptable. They are not the easiest rifles to bed, so if you wish to pursue that route, and have never done a 77 before, you may want to turn it over to someone who has experience with them, or just plain trade it on something else. Handloading not giving you better groups or haven't you gone that way? Rugers are fine rifles, in my opinion, but may need a little tinkerin' as Rammer said, and/or some well-worked up handloads.
By the way, I gave that 77 .270 to a friend of mine upon the birth of his first son, to become the lad's deer gun as he grew older. They still have it.
