Hi I am new here and have some questions that need good people to answer so I will be making some threads. Ok I have a 257 weatherby made from a m77 action and a 27 inch north west barrel and a lam stock. I am just getting some brass together I just got some Federal nickel brass cheap. The big question I want to ask I have a chance of getting some PMC 257 weatherby brass quit a bit but he wants to sell it all. OK I have looked around about to see if I could find anything about the brass ,I can not find anything about it, people even told me this brass was never made. IS this brass good bad or ugly , worth buying a large bit or not please help.
