Actually the Wylde chamber is a slightly generous 223 chamber with a slightly longer freebore/throat/lead than the 5.56.

You use to be able to find a K31 Swiss for under $200. They shoot the 7.5x55 which is similar to a 308 win.
K31 is going to be hands down the leader. K31's will shoot better than most ~$1,000 bolt action rifles.
