Not without some help
No. The stocks are not interchangeable. Boyds make some nice aftermarket stocks for the Remington 597 as well as the Ruger 10/22. The Ruger 10/22 has all sorts of aftermarket parts to customize the look and performance of your 10/22. The Remington 597 is just now beginning to get more aftermarket products available to customize your rifle.
No
The Winchester Magnum Rimfire is a larger round, and is capable of producing twice as much energy as the .22lr. I do believe that Ruger is making a rifle capable of handling the .22WMR, but a standard .22lr rifle is incapable of safely firing the .22WMR.
Yes
The Sabatti .22 LR and the Ruger 10/22 are not interchangeable. While both are .22 caliber firearms, they are different designs with distinct specifications, parts, and accessories. The Ruger 10/22 has a large aftermarket support, but components from the Sabatti will not fit or function in the Ruger system and vice versa. Always refer to manufacturer specifications for compatibility information.
