Are you going to be competing in rimfire benchrest? Get on a rimfire site and find out what the winners are using. You've got to make weight in different catagories too. Competition quickly sorts out the good from the bad, the appropriate from the inappropriate, and even the best deals for the money. Something about a scoreboard that strips away the BS.
I took a Anschutz built for Rimfire benchrest on trade awhile back, and it was fitted with a 20 X Leupold benchrest scope. That could be an antique by todays standards as far as I know, but is a revelation in what propose built tools can be.
