I have a Ruger 77 in a 257 Roberts AI. It shoots really well. I did not buy the gun new - it is one of the older creations. I also have a 7x57 Ruger in the old style that I had a hard time getting to shoot tight groups, but eventually found the right load for it. I think some of the older Rugers can be a little more challenging - but the 257 Roberts AI is a tack driver for me.
