Original poster which .22 question
Ruger's Mark III slab sided target is a great entry level competition gun for the $400-450 range. It will take you a long time to out shoot the gun. It will probably be my next gun. It is a challenge to learn to break down after a few times it is quite easy, just different.
I have not shot as many of the Brownings buck mark so I can't attest to it as well.
I just know all of my research for "cheap comp pistol" always brings me back to the Ruger. I am very pleased with all of my Rugers, well built and accurate.
