Daryl:
I have been buying from Buffalo Arms for years. Great place for brass and bullets for the oldy goldy guns. I use their 12.7X44R (My SXS Husky combo), .43 Spanish and .43 Mauser, 6.5X53R brass. I also have purchased different jacketed and cast bullets. I have not yet been disappointed. OH!, also dies.
The other one is Rocky Mountain Arms for turned specialty cases. It took them a while, but I now have 40 perfect (headstamped also!) pieces of brass for my 9,5 x56R for my Fr. Newmeyer SXS combo.
Now that all 11 of my inlaws are gone back to SA, I intend to start working with my guns again.
Hope of hopes!!
