gun values

[goforchrome]

There seems to be some very knowledgeable gun owners on this board so here goes...
I have a military surplus Springfield 3006 A303 that was manufactured by Remington and it's in pretty good condition.
I am thinking about selling/trading for centerfire hunting rifle and wonder what this gun is worth.
I know there is probably a broad range and you may need more info but figured I'd start with that.
Any help appreciated.
Thanks.

You might look at www.gunbroker.com or www.gunsamerica.com They both run a bit high but will give you an idea.
