d2wing: If you're interesting in benchrest, not just a rifle that shoots good (which the CZ and Savages certainly do), then the best advice I can give you is to head over to the Benchrest Forum classifieds (
http://benchrest.com/class/index.php?a=5&b=199) and buy a used dedicated benchrest rifle.
If you want to go new, good rifles (as starters) include:
Anschutz 54-series action
Remington 40X action
Suhl150 action
and a number of custom actions out there like Turbo.
Then you'll want a good barrel, and while some rifles shoot really good from the factory, the quality control isn't tight enough to guarantee a shooter. Can you imagine, rebarreling a new Anschutz? People do it.
Add a custom stock, a bedding job, and of course a top quality trigger and stick a tuner on the barrel and *hopefully* you have a benchrest rifle! (Which is why it's better to buy your first one used and have all this already done to it). Then you need a good front rest and rear bag.
So anyway, if you're not competing, you don't need to do all that. Instead, focus on getting the most out of your setup. To do this, you'll want to buy a good rifle, of which the Savage or the CZ are good suggestions, as is the Kimber 82G. Get the trigger as light as you can safely. Tune the rifle by shooting groups and measuring the sizes, experimenting with:
-ammo
-torque on the action screws (get a FAT or better torque screwdriver)
-hold of the rifle
Try to be as consistent as possible and shoot at least five 5-shot groups to prove anything works better than another. Do your testing at 25 yards to minimize the wind, but when you think you have something, take it out to 50 for final testing.
My bench gun, which is not what I would call a top-notch gun, would shoot 0.25" 5-shot groups at 50 yards (measured center-to-center using OnTarget software) using pretty much any decent ammo (Eley yellow box or better) and it would do so *consistently*. Now that it's been tuned, it will do a little better than that with Eley black box of the slower lots or Federal UM22.
