I find it really interesting. the Aussie thinks Norma, a Swedish made brass, makes Nosler. Since Nosler brass is made in Washington state (USA) and Nosler company owns Silver State Armory (SSA brass), also made in Washington State. Nosler and SSA brass come in the same bulk and boxed amounts. I seem to find fallacy in the Aussie's thinking/assertion.
Nosler comes in bulk (un-prepped brass) in bags of 250, 100, or 50 depending on caliber, and in 100, 50, and 25 count boxes (prepped) depending on caliber. they guarantee 1/2 grain maximum spread between lightest and heaviest piece in the box.
I have bought both prepped and un prepped Nosler brass. I find the un-prepped almost not worth prepping but it does need a little cleaning up from time to time. All in all, a wonderful brass to start with.
