Unfortunatly,, Levi's right about the 452's feeding problems..
I got one in a trade that wouldn't feed any of the HP's I tried. I tried the fixes that they have pinned over on RimfireCentral without any luck. I could swear I had that magazine apart a hundred times,,, probably more like twenty,,, but enough to totally pizz me off.
I like CZ's and really wanted that rifle to work out so I bought a new Magazine from CZ,,,, same same.. Sent it back and no difference.
I finally gave up and dumped it,but I did tell the guy I sold it to that it only liked to feed Polly Tiped bullets and he was fine with that...
To bad cause I'm positive that CZ is aware of the problem and doesn't do anything to solve it. At least not that I'm aware of...
The Quad's supposed to be super accurate (well for a 22mag) but I just can't bring myself to buy a plastic stocked hunting rig... I'm kinda looking at the Ruger 94/22M lever action for shooting out treed Coons and Cats.. Probably not as accurate as alot of choices, but it's lite-weight and very handy.. Should be fine for my needs..
Good Luck,,, and let us what you deceide..
