just seeing whether a single shot rifle would be more accurate than a lever gun or a ruger bolt gun.
There are different lever guns and different bolt guns. I would say Contenders generally can be made to shoot better than the majority of lever guns and a lot of bolt guns.
You also have to understand cartridge limitations. Take a 17 HMR for instance. Groups could easily be in the half inch range at 50 yards and more like 10 feet at 400 yards. It's hard to get things like the 44 Remington Magnum to shoot consistently under an inch at 100 yards but easy with a 204 Ruger.
