Well I have examples of all three.
1-Marlin 39A Golden
1-Ruger 10/22 stainless bone stock
1-Ruger 10/22 fully decked out ($600+ in it)
1-CZ 452 with a trigger job (Sweetest trigger I have ever felt)
Tough choice for me. The Marlin and the CZ feel more like "real" guns. They have more pride of ownership. The CZ is EXTREMELY accurate with any 40 grain .22 I feed it.
A bone stock 10/22 is fun but not all that moving. Spending the time and money to build it into something else is immensely fun and satisfying but gets pricey.
So if I could have only one plinker...........
I would rule out the stock 10/22. Just not as cool or as much pride of ownership as the others and costs a decent amount to build into something personal.
I would rule out the CZ 452 only because I feel it is a more serious gun then for plinking all around duty. If you go with a 452 spend the money to put good glass on it and start shooting single holes with it.
That leaves me with the Marlin 39 as the best all around plinker. Here is why.
1)19 rounds of .22 long rifle, thats a lot of ammo on board.
2)Feels like a real, high quality, well made firearm....because it is.
3)Shines with iron sights. Maybe add a peep sight or buckhorn style but is basically good to go out of the box.
4)It is a lever gun and not only do they look good they are just spectacular fun to cycle. Shoot fast or slow.
5)Great gun for indoor or outdoor ranges.
6)All in all the most versitile of the three IMO
So basically the Marlin edges out the CZ but only by a nose and only because I am placing an emphasis on it being a plinker.
CZ 452 Varmint with Bushnell Elite Scope.
10/22s from affordable plinker to you paid how much for that?
