I have had a Mauser 210, many Ruger with sporter and bull barrel, and Browning A bolt.

The Mauser 210 was unreal to say the least, the browning A bolt a close second, and a couple of the Rugers very close to thirds. The Rugers are hit and miss, but all of them were very accurate.

Also, a Marlin 25 M clip feed was shocking at how accurate it was.

Ammo type is critical, but all the most accurate loved the same ammo, the Winchester 40g HP.

Many do not realize that the 22 mag has to be cleaned. If you ever shoot a plated lead bullet in it, you clean immediately after shooting every time because those copper plated lead bullets lead up the barrel quickly.
