If you've never shot F-Class before, I would say buy the Savage F-Class rifle, which comes in 6.5x284 and you'd be good to go for not alot of cash, so far as prices for match rifles go. Once you've got yourself into the sport and have established preferences for equipment, you can branch out to new calibers or different rifles. Also, you can get a Savage right now, compared to six or seven months from now if you have a rifle built just for you.
