Hi "Bianchi",
The packaging simply says "KVB-7", "LR Standard" there are no further abbreviations.
The outer packaging is red & white, and has the bar code: 4 600053 004275, LOT 1-03.
Some more recent ones from John Carmichael of HPS have the same bar code, from LOT 24-10.
The newer packaging is broadly similar, more trade marks and with less emphasis on being non-corrosive.
I've never felt the need to use magnums in the .284 or WSM, but several other guys swear by magnums...so you decide..
Cheers.
