I got this bottom metal for my 300 Winchester Magnum, and I'm really happy with how it looks, fit it, etc. However (and I understand that even with modern machining techniques, there will still be some issues) there is a slight burr that formed on the forward interior of the magazine well that prevents me from seating the mag. I think I could scrape/file it down, but would I be better served to just return the piece? Is this a common problem with their bottom metals?
