Nickel plated.Hard to see on phone is it just discoloration of brass? Almost looks like it was exposed to water or some chemical. Was box in new condition? If not, it could have happened after it left the warehouse. I'd call and tell them about it. Probably get one or more new boxes for your trouble.
Like finding Waldo before your directions. I found it before I read yours, but that was fun!look 4 from the left and one down. Primer isn't seated properly.
Because of posts like this on here I check every box(more expensive ones) that I buy. Just got Gold Dot .45 today and I looked like the lady in the market examining every egg. I am sure they will rectify the situation.yeah, I"ll be sure to contact them. Glad I could give you guys a fun scavenger hunt
