Well now you've done it. For what you've described, a 6.5 to .30cal will fit the bill. Anything from the .30-06 to the 6.5 Weatherby Tachometer will work with good bullets in the right spot. If I had no rifles and wanted to kill deer, antelope, and elk I'd go with a Tikka Stainless in 7-08, 270, or -06. My wife but down a dandy Caribou with a 140AB from her Tikka 7-08. For the money, it's about the best factory rifle you can get. If you don't mind the extra recoil, a 7mm Magnum will work just as well and shoot a bit flatter.
