Today, I was able to spend about 4 hours at the range. Weather was perfect, just wish my aim was too. As I was picking up my brass, I would pick up the brass that was left behind. I have done this before, but it just looked to be more than I have seen before. I have seen many people crying about how they can NOT find any range brass now. At the end of the day, a group came in just before closing, fired off a bunch of 223 and left. I got 79 pieces from them alone. I walked away with a few that I didn't know what it is at first, but was able to find in books or web. I have two that I am not 100% on. They look like 30 Luger, but they are a bit long, @ .978 and .965. Anybody got any idea what I am looking at? I also had a thought as I was looking at a 223 with a split neck. This brass would be perfect for someone that was trying to make 300 blackout. I have been thinking that I would practice annealing with my junk brass first, but trading for other brass may be even better.
