RE: Ruger 10/22
The VERY 1st thing I would recommend is to change the hammer to get a much better, easier to shoot accurately trigger pull and scope it. Later on, you might consider replacing the barrel with a match quality barrel & an Hogue stock for it. The barrel will shoot any kind of ammo better than the loose chambered factory barrel, but will really shine when you find ammo it likes. I currently have 3 of them, all reworked.
