If it is a Pro Hunter its worth a little more. In my area they tend to go for $699 new give or take a few. I just purchased two VXIII 2.5x8's for $385 each. I love that scope. I have a few on guns right now and they have been great. I hope that give you a new reference to work with. They are wonderful guns. You should not have a problem selling that package at all.
What its worth and what you can get for it is sometimes two different prices's.
I have bought 5 Encores in the past couple years. SIx month's ago I paid $250. for a stainless frame and they come available from time to time for $300. Can buy a barrel every day for $300. new. The Leupold Scope is worth $250-$300 used.
