...and Many/most Marlin fans will gladly shoot a stock mdl. 60 up against a stock 10/22 for half the $$. (

that ought to start a debate!lol)
Marlin 60 can be found used in excellent shape for $90-$120, or buy a new one for $130! If you want a center-fire Rifle, The options are as vast as your money.
even AFTER you buy a center-fire rifle, you can use the .22 rifles for learning technique and accuracy.
Some rifles offer "Switch-barrel" ability which enables you to use different caliber barrels on the same gun frame/stock. This option is starting to prove itself well.
as stated above: try shouldering as many styles as you can and something will stick just right for you. The suggestion of getting a .308 cal. rifle is appealing to many shooter as a great caliber. I have Milsurp and factory rifles and all of them shoot as intended. You are the best judge of what will work for you. There is no such thing as a Magic Gun for All needs. some come close! Good luck!
