Hi Mke,
I'm sorry to see this but glad you came out relatively unscathed!
I thought I'd share the contact info for this shop near me. I wish you and I were closer as you could swing by this place, but if nothing else he may be able to provide you some great info for a specialist that's closer to you. Or he can certainly provide a new stock for you and give you some great info. They specialize in gun stocks and have been around since the 70's or early 80's. He has an amazing selection of stocks and a very impressive selection of wood overall.

Congrats on the bear! That's a great picture as well and I can't imagine moving it 3/4 of a mile. A whitetail is enough for me though I've always wanted to harvest a bear.
