Thankyou! Some one else already hooked me up with brass. Yep my Ruger .338WM is the original M77 with the tang safety. The wood and bluing are beautiful. I dropped it off today to get the barrel threaded, already submitted the E-File for a .338 can.I may be able to help you with the brass. How many do you you need. I may have one can of 19 but due to hazmat regulations cant ship that.
PM me if you need any more information. Your 338 I think is thumb safety. They are nice rifles.
