I speak from experiance on the 10/22mag , there is a reason they are discontinued . I had a huge thing with 10/22s about 6/7/8 years back(somewhere the start of CGN I beleive ) probley built upwards of 20 regular 10/22s , a couple of 10/22lr-> 22mag conversions and a few of 10/22mags as well . My conversions functioned better than the real deal.
I had both models of the 22mags single and dual extractors, I know the actions like the back of my hand and they did not function all that great . I also found that the barrel Hole was also milled of center on ever one I have owned an played with and the barrel Canted off to one side , witch ment for for heavy windage adjustment. I could make them shoot ,and put a tonne of cash into them and had a great time doing it ............
I love the 10/22 and will buy guns to have a set , but the (2) 22 mag semis that sit in my safe is a target model..................... Remington 597.
No problems what so ever and I have worked the one , and keep the other just to have .
get the 597 mag
