There has been a lot of good advice given in this thread. Here's what I think I'm settled on:
Savage 11 Hog Hunter .308 20" medium/heavy barrel with threaded muzzle. $410-$450.00
Vortex Viper HS-T 4-16x44. ~$550.00-$600.00
That leaves $450-$500 for rings, dies,ammo and maybe a bipod for bench work. This setup would make for a decent hunting/target rifle out to 600 yds. The only down side to the rifle is the internal magazine and cheap stock, but for $400-$450 you can't have it all.
