I hope you can find some. I have about 300 but not for sale. I took me years to acquire it but have not been able to find any for about 5-6 years.I was able to find small amounts at gun shows and would buy what was available.
I took it for granted since it was a prestigious gun as a mark 5 and caliber, new was wanted.
Just curious though, how can you tell the difference from once fired brass to eighth fired brass, especially if it was tumbled and polished? Not trying to be smart, just wanting to know.
30 years ago I heard folks would shoot blue magics a dozen times and then wash them in a pillow case in the washer and then dry them in the dryer and sell them as once fired. Although must folks are honest, but gun show salesman? Bob
