Been using a new 1000 box for a couple months. All have some degree of purple, they all perform the same. Need to check the 215 standards for the purple Monday. This would be a good question for a manufacturer rep being a member of this forum.
Yeah, I can't find 210s ! My package is also red, with a dark blue accent stripe on one side. Also can't find the 210M, which I think are the match primers. I'd love to get either one!
Mine have the purple coloring, and some have the "blob" too. All I know is they're producing phenomenal consistency in my 338 lapua improved. Out of 75 rounds recorded with the lab radar, the biggest ES has been 13fps.
