.50 Bmg identification

Hi All
Need help identifying these headstamps?, I take it they are both the same manufacturer but the first one without the RD stamp

Brian, your cases were made in the Dominican Republic. To what I understood these were around on the US commercial market for longer.

These apparently have the reputation of being some of the poorest quality .50BMG cartridges ever made. While they are an interesting collector cartridge, I have seen it posted on the internet that shooting them is not recommended.

I am sure I remember reading that firing these in a civilian owned Barrett .50BMG rifle will invalidate the warranty. Is anyone able to supply any documented proof of that?
