New to forum, recently came across this site after spendings weeks on weeks trying to find some advice/help/direction. My grandfather recently passed away and left me his collection of arms. Before he passed, he wanted to build out this winchester model 70 that he bought from a friend. I recently purchased a deer tag to go hunt south of the border with friends and thought it would be really awesome if I finished this rifle and shot a nice coues deer with it. The search begins of trying to find out what this rifle is. Here's what I know. Its a winchester model 70 .300 wsm, stamped with distributed by olin corp, and currently sits on a shadow style stock. Looking at winchester's past model 70's I am not sure as to if its an Ultimate Shadow or Black Shadow. Regardless, it currently has a custom break on it from a local gunsmith. I have the optics taken care of already. The issue I am having is finding who provides parts for this particular rifle. I have left multiple voicemails with the Winchester historian and haven't heard back. My primary goal is to have a solid hunting rifle that is capable of 700-800 yards, I know 90% of this is the shooter. I would really appreciate some direction or help on who I need to talk with.
