Out to 300yds. the .270Win. or 30-06 are all you will ever need for any deer hunting.
Now, while either cartridge could also be used to 400yds, if the shooter is capable, I'd
probably want a little more punch for those extended ranges, and maybe go with the
7mm Rem.Mag. My personal max. is 300yds. I won't shoot at big game beyond that
range so my .270 or .308 work just fine.
As for the make/model of rifle, well there's just a bunch of good quality rifles out there.
Check 'em out, and see which feels right to you, and is within your budget. Most any
make is going to be available in the three cartridge chamberings mentioned. Personally,
I like the Rem.700 LSS Mtn. rifle (.270 & 30-06 available), Ruger 77s, and the Sako.
As noted, the Savage is hard to beat for the price, and accuracy.
Don't skimp on the optics - good quality glass is just as important as the quality of your
rifle.
