My grandfather gave me all the contents of his gunsmith business from when it closed about 20 years ago in PA and I have been just getting through some of it. Now I'm no gunsmith and I would attempt to do what the artist do but I can sort out that there is everything needed to build a bolt action .284 Winchester rifle in there. Has anyone ever had a rifle or experience with the .284? I know it falls into the 7mm club somewhere....
