Stevens 200 in the caliber you like. My old hunting partner bought a Savage package rifle with scope and sling in 7mm Rem mag for about $370.00 a few months ago. It came with the accu-trigger. It shoots nice groups and seems like a lot of gun for the money.
I like the 243 and lots of folks like the 25-06, 270 or 280 Remington. If your magnum oriented the 7mm Rem mag has near the same recoil as the 06 and then there's always the great 300 Win mag.
My friend with the ATR he bought at Wally world now laments that he'd rather have gotten the Stevens 200 now that he's had the ATR for a while.
Keep in mind that with the Stevens or Savage you can switch out barrels (calibers) in about 15 minutes with a go headspace gauge, barrel nut wrench and barrel vice.
