Look for a used model 10 in 308 or 243 Win. Then contact Jim an Northland Shooters Supply Northland Shooters Supply
Jim stocks barrels from Shilen and Criterion, so you don't have to wait 6 months for your barrel. Believe me, that is the "regular" lead time. From either it will be around $300. You want an 8 twist. The Savage barrels are 1:9.25 but that is not good enough to shoot the "real" high BC bullets with adequate stability (the Long 95gr and 105gr VLD's or Sierra Match King bullets). The barrel should also be 26" long to get good velocity for longer range shooting.
Jim also has all the tools to do all your own barrel work. He has the Savage Nut wrench as well as a great receiver wrench. If you use it once it would have paid for itself compared to going to a gunsmith. To set headspace, you need a go gauge for your chamber. Those are $30 at mansonreamers.com.
If you have nothing to reload and want to get started with some decent ammo, you can buy HSM ammo which is loaded with Berger bullets at Midway HSM Trophy Gold Ammo 243 Winchester 95 Grain Berger Hunting VLD Hollow
If you think the price is steep, bear in mind that "regular" factory ammo is just a few $ cheaper but definitely not comparable in ballistics. You can get a reloading setup for about $500, then you have to buy powder, bullets, brass, primers and a set of dies. So its not cheap going in, but once you are set up, you reload for a fraction of the price of factory ammo and remember, this is not chinese or Russian "blasting" ammo. This is stuff that follows the "one shot 1 kill" mentality.
