I bought an NEF .223 just for this purpose. I got the Survivor for $200 at Walmart.
With the scope, and shooting sticks, it's a real sweet setup. It shoots cheap winchester 45gr hp very well. Eventually I want to camo the stock.
If you don't require cheap ammo, look into the new Ruger .204 cartridge. The 32gr bullet moves over 4000 fps!! You can get an NEF in that chamber for under $200 too.
