I had a 64 TR SR and I wasn't impressed with the accuracy. Cannot imagine they changed the barrel. Pulling the barrel to remove the bolt is a poor design. I'd still take a 10/22 over it.
I know it's no 10/22, but by the time you have a bull barrel and chassis on one of those, you are way past 1k... Plus bonus points for 20rnds stick mags.
So, who's got one, and how is it?
