From Kris Carson, Director of Public Affairs at Remington in Lonoke:
The brass shell and brass primer are used in our newest loading facility here in Lonoke. The dot added after "R-P" is what we use to distinguish between the two types of loaders. The primer color can change from nickel to brass, but typically will be brass.

From Kris Carson, Director of Public Affairs at Remington in Lonoke:
The brass shell and brass primer are used in our newest loading facility here in Lonoke. The dot added after "R-P" is what we use to distinguish between the two types of loaders. The dot indicates that the cartridge was loaded in the new section of the facility. No dot indicates the cartridge was loaded in the original section of the facility.
The primer color can change from nickel to brass, but typically will be brass.
