RE: What Rifle?
14? I'd suggest a .243 made by Savage. Savage rifles are legendary for their accuracy, straight out of the box.
Also, you mention the terrain where you hunt. It's a good idea to match the rifle to the terrain where you hunt. You wouldn't want to bring a massive .338 Magnum witha 4-12 x 50AO scope into the heavy brush, briars and thickets. Just the same... You wouldn't want to bring an old open sighted .30-30 out into the open ridges and rolling fields, to take down a Mule Deer at 300 yards.
The .243 is perfect for overlooking a field edge where you can shoot 200 yards or more. It is a flat shooting cartridge with little to no recoil. Keep the shot right in the chest cavity, and you will have venison!
If you hunt in the deep woods, briars, and thick stuff, the timeless classic, historical, .30-30 shines here. I still have my old Marlin .30-30 and use it just for that purpose. It's real lightweight, easy to carry, and can come right up to the shoulder to crack off a shot in an instant. There's just something about an old lever gun with open sights. You're following in the footsteps of generations of hunters before you.
Now, besides my old Marlin .30-30, I also have a Savage in .308 with a nice Bushnell 3-9x40 scope, that I use for the pastures, field edges, up on the ridgetops, etc... I use the .308 everywhere that I don't use the old .30-30.
Hope this helps...
