I've got no heartburn for the Marlin or the Savage, a lot of gun for the money, I am very fond of CZ's 452, much higher quality, fit and finish, on gunbroker, 250 to 450 bucks depending on caliber and finish. I'm not big on ruger bolt guns, but there rimfires do shoot pretty well and have easily replaceable barrels to either change calibers or for more accuracy.
I know this is out of your budget, but the Anschutz .17 hmr is outstanding. I'm shooting on the 200 yard line and waiting for my turn to set my target up, am talking to the guy next to me who is shooting one. Ceasefire comes and I go down to post my target and look at his 1.5" groups ( 5 shot ), about 4 groups on the target, none of them stink. Went home an started pricing them, 700 bones or so, but if I am going to get groups like that, well maybe. Yes it was a sporter, not a heavy barrel.
As to caliber, .22lr is boring but all of the arguments are valid. I like the HMR, but if I did not have a .22lr, I would'nt buy the 17, the 17 HMR is damn fun for shooting crows, they blow up real good.
Side note: if you have a DCM club around to compete in, you can buy U.S. .22lr target rifles for a good price, Remington, Mossberg, even Kimber. Have fun making up your mind while we muddy the waters.
