10 MM brass
I was pleasantly pleased to find a large overrun of this brass. However, I soon discovered and understand why. There were 90 pieces of small primer brass in with the large primer brass that was ordered and that 9is understandable. I was also quite happy with the fact that I have only found 1 piece of brass that was split!
Very happy with my purchase and would be happy to send the small primer brass back if requested to do so.
