45 ACP ammo

There is approximately 510 rounds (boxed and loose) of 45 ACP ammo.  I went through some of the ammo and it appears to be a mix of potential non-corrosive and corrosive. For example, these seem to be the common headstamps:

FC 64 & RA 63 which would be non-corrosive as they appear to be produced after the 1950's.

REM-UMC 45 ACP may be corrosive as these rounds may have been produced between 1912 - 1952.

Please note that I am not an expert and I am relying on 3rd party information to help identify the rounds.

Would prefer to sell as a lot.  Must have PAL.
