I had an interesting day today. I found 4 boxes of 6mm Remington superformance ammo with 95gr SST (that my neighbor gave me about 5 years ago ). I need 257 Roberts brass, so I figured this 6mm would be a good donor. I pulled the bullets and deprimed all of them. Necked them up to 257 and reprimed them with the same primers I had just popped out of them. Now I just need to load and fire form the brass.
