I would keep my eye on here at at www.6mmbr.com
for a good used straight 6br. That caliber is easy on the wallet to shoot, reload for and will work for great paper punching in the 600 and 1000 yard BR, f class matches and ground hog matches.
You can buy a good used savage 12 bvss or 12 low profile varminter, for around $500 or less, go to sharpshooter supply and buy a 6 BR chambered barrel for $300 and another bolt head for under $40. Buy the Ken Farrel 20 MOA base for $70 or the leupold double dovetail bases and burris signature rings and that will leave $1000 for scope which a good used one can be had for half that.
$500 left over for bullets, cases, primer and reloading misc.
