Seems that a CZ 457 with a Lilja barrel and Eley Match are a decent combo. Start wth the CZ Synthetic, add the barrel, and mount in a MDT XRS chassis and you'd have essentially the same setup as the shooter in the videos below for less money than a 700-based footprint rifle setup.

The MDT XRS is not even close to the manners stock.
