.22 semi-auto at the range???
I will add that I also like .22 revolvers,I have a S&W mod. 17 and a mod.34
how ever the question was semi-auto.
My start .22 was a .22 semi-auto was a Vostok (U.S.S.R) I have had and used it for 44 years,it still gets a lot of use and has been trouble free.
Unfortunately you will probably never see one.
My serious .22 is a Hammerli 207 International.
Now that I have run on, if I were going to start now I expect I would go with a Ruger,any that I have used could stand a little trigger work but they shoot good.
When we remember we are all mad, the mysteries disappear and life stands explained.
