100-1000 depending on specifics
depending on condition, anywhere from $100 to $1000. These ARE collectable firearms, but value is based on condition and originality.
I'm not quite sure about the 3006, but I know that the longest recorded kill shot with a .308 was at about one and a half miles, possibly more.
50-500 USD or so
100-400 or so
You sure this isn't an EJN 757 instead of a JEN 757? I have a EJN 757 in 3006 and would also be interested in any info. for this rifle.
