I sent a Ruger MKII off and had a 260 tube installed. This was before the run of Hawkeye's that Ruger made. Eddie F is coating that gun and I'm also going to send him the McWoody on order for a bedding job. That rifle has a #2 Douglas with an 8 twist -- 24" barrel.
I'm also giving thought to a light 260 too. Something at 21-22", 6.5 to 7 all up. Probably on a 700 action.
A couple of other choices to consider -- Cooper and MRC. The local shop has a MRC stainless AWR new on the shelf. It's a nice rifle! Had I seen the MRC 260 before I started the Ruger project, the MRC would be in my safe...
