I recently picked up a brand new Savage 10FP in 308. It has the standard 10fp matte textured coating on it. What surprised me was the inside of the barrel was black. I figured at first it was just a rust preventative coating/lube but when I started cleaning it I was surprised to find it very hard to remove. I am wondering if it was overspray from the matte texture coating or if it was just a really thick protective coat? I know the gun was brand new as I watched the box seal break myself. Does anyone have any experience with this? I did get the gunk cleaned out and the gun shoots great.
