I was watching "Sighting In" on the Outdoor Channel tonight and in their segment on Begara Barrels they showed some proof loads being fired. The entire case head and primer was painted a bright red. Is this an industry standard? Or is it just something that this barrel maker uses to tell proof loads from standard loads?
I ask this question because a friend of mine came up with some 5.56mm loads with the case heads and primers painted red and has so far been unable to identify them. The stamping on the case heads appear to be cyric writting suggesting Eastern European or Russian manufacture. We have been unable to match the head stamps to any references that we have available. I do not have any pictures available of the head stamps.
Any help is greatly appreciated. Thank You.
