Two otherwise identical .280 UK Observation rounds; GMCS, brass case and primer, ring crimp, purple annulus, (RG 48 .280). Is there any reason for the significant difference in the tip color application?
I also posted this on the IAA Forum. I got an answer there from Tony, but I thought to post it here also, for info, and just in case there's a hidden expert with secret knowledge.
I had these all together for another purpose, but I thought a group pic might be interesting.
