Not sure if this is posted anywhere on this forum but I follow this chart to determine corrosive primer if I have the lot# and headstamp.

How do you tell the difference between the two? I have some DM, I can't remember the date right off hand. Were they in production at different times?

I have found regular old fashioned Windex with ammonia works very well to clean the salts out after shooting corrosive ammo. I liberally spray it down the bore and patch out, repeating several times followed by any oil. Never had any rust issues either.
