I've got a Ruger 77 ultra light in 257 Roberts. Had a trigger job, barrel recrowned and put it in a Brown Precision stock (glass bedded too) but have been unable to get it to shoot like I want. I acquired a Remington Model 7 in 7mm-08 that shoots lights out and has rendered the 257 Roberts a moot point. I want to rebarrel it to a larger, more powerful caliber and I'm wondering what will work in the length action I have. I was particularly wondering about the new 300 Winchester Short Magnum. Would this work or what would be my best bet in a 30 to 35 caliber cartridge? I'm leaning toward a 22 inch barrel and have always used Shilen. Is there anything better out there?
