RE: help me find my first rifle
If you like to shoot at the range and want practice time the .308 is probably about the best there is because the ammo is cheap in mil surp. I would take a look around and see if you can find a Winchester M70 out there. You should be able to duck way below that $700 and have the trigger smithed. I just had one done and that trigger is exceptional.
The ruger is a beautiful rifle in stainless and laminate but they run higher and you'll have to put a new trigger in it whick will cost you more. If you really want to spend some dough take a look at the Kimber Montana.
