CZ 452 American with 4X scope at 25 yards, last Saturday, very windy. The top right circle is five shots. The middle and bottom circle are 3 shots each. All three circles were shot off the bag. The squirrels were shot unsupported.
My CZ outshoots my Browning BLR and Ruger 10/22. I think it is about equal to my Browning A-bolt in the accuracy department. I would have to get a higher power rimfire scope to find out which one was better. Sorry, I have not owned, nor shot the Marlin.
