value of Rem 700 458 Win Mag & ammo

I am interested in determining the value of my Rem 700 Safari grade 458 Win Mag. Great shape; shot fewer than 50 times. Also 26.5 boxes (20 rounds per box) of Super X 510 Gr Soft Point.

If someone can help me, please call (520) 393-1783 or send your tele number to my e account at RDK11@Cornell.Edu.

Thanks in advance.
