I haven't bought many new rifles but I had a weak moment about a year ago and bought a new in the box Mod 70 375h&H Alaskan. It still has the sticker on the barrel and I haven't shot it yet. I was cleaning my guns and decided to give the new Winny a wipe down. I was shocked when I ran a patch through the barrel. It was absolutely filthy. It took several brushings and multiple patches to get it clean and it had traces of copper. Does the factory shoot several rounds and then box them up dirty? I assume they test fire each weapon but this looked more like a box instead of a round or two. Or maybe I bought a "Friday" rifle?
