Gradous Rifles builds absolute hammers. They have built me two 300's and a 338. They know how to get the best accuracy from the Norma Mags. Call Jon Slagle, who is an absolute gentleman, is the person to contact..
Lots of great Smith's around these days. As so many others have said, look for one that's close and HIGHLY suggested. If there isn't one close that you like ship it off to any of the ones you see alot on here.....
