Free range brass
like free range chickens, is a Good Thing.
Kscotto asked, however, what is the BEST brass.
For my fooling-around rifles and ammo, free range brass is the way to go. (E. g. my SKS.) However, for my "serious" rifles, it's Lapua all the way, and Norma if Lapua doesn't make a given cartridge. There is a demonstrable difference in accuracy when using the hi-grade stuff.
Dead-nuts consistent, perfectly annealed, drilled flash holes, what (besides the price) is not to like??
Have heard good things about the Nosler brass but have yet to deal with it personally.
