Wow - lots of vague here. Condition is "ok"? Is it truly in full military?
If it's a 30" ish barrel, then it's not in 8X57, because it's a rifle, not a carbine. It's 95% likely to be in 8X56R, which looks nothing like 30-06, but to a newbie it could.
Price will be at most $300, maybe a lot less. Sorry I can't be more specific.
