I just in 100 rounds of once fired 8x56RS brass, its from Diamond K Brass. it looks brand new (but with a fired primer in the case) and it seems to be all PPU brass. A little cheaper than new brass but I did save $10.00. I picked up some range lead this afternoon I'm trying to cook it down now. It's kinda working. I'll load it and them anneal this batch of brass. I'll be trying ACC 2400 on the next batch also.
