guy that SBR'ed it for the article?
it for most brass is the 70/30 brass alloy, that is it is 70% copper with 30% zinc. While their may be a little bit of difference between manufacturers it is vary close to this range. This is a good casting brass too and is mostly known as yellow brass, I do some various home foundry work and I'll range rat any brass left at the range when I go, even the .22lr caseing.
Nah i just shoots a five-seven and a PS90 and talks about it then gives a little bit of of load data, it's not that interesting.
