In order to answer your question correctly I would need to know the model of savage rifle that is chambered in .243 Win.and the overall condition of the rifle to give you a half way decent value.
The current value of a remington model 600 in .243 winchester caliber is between 160 dollars for a rifle with 60%of its original finish remaining up to 475 dollars for a rifle with 100% original finish remaining.
