My brother gave me a box of 45ACP brass. There were 4 zip locks with 250 pieces in each. I started prepping them tonight and found that some were head stamped RA 66 match. A google search says Remington Arms brass. When I deprimed the inside of the primer and the bottom of the primer pocket are white, and it is some kind of powder as it is accumulating on my press. Likely some kind of corrosion. The brass is in excellent shape otherwise and does not appear to be old enough to be made in 1966. They are all clean enough other than the pockets that I would only give a couple of hours in the vibratory cleaner and load. I think maybe some time with the stainless pins may be a good idea. Any thoughts would be appreciated!
