That's a beautiful gun, and I love Marlins, but it is not the most accurate 22. Ruger 10/22's have a firm hold on that spot.
Just got my wife a new 10/22 a couple of weeks ago. We shall see which is is the most accurate. We have been at the rim fire range at our gun club (big rock gun club) for the past 6 Sundays in a row (with 22's borrowed from my Pops) so since we enjoy it so much, we got a couple of our own.
Much cheaper than shooting our AR's.
They have several of the steel spinner & resetting targets at the club for 22's and we purchased one (and our neighbors bought 2) for using at the house. I plan to do some "plinking" in the near future.
