Home Forums Miscellaneous Topics Image Gallery Thomas Turner .500?

Hey all. I'm trying to get pictures to work. The bore is like new with 9 wide grooves. Both hammers and safeties work well. Has anyone have a split .500 nitro case that I could buy? I do not want to get a box of brass if I'm wrong on the caliber. It has mixed hammers and one of the firing pins is not retained. Would that cause an issue when firing? This outta be a hoot ta shoot!
