Are you set on a new rifle??
You could get a Rem. 40x in 308 for around that price. You could also get into a 300 mag with a trued Rem. action and match grade barrel. Go to benchrest.com click on complete rifles and go to shooters corner.
They have a ton of rifles that will do what you want for around $800.
I personally love Rem. rifles. Most smiths know how to work on them and the parts are very common.
Good luck.
