I've gotten fussier over the years.
For 7.62mm NATO/.308 Winchester, it's either Lapua or Lake City. If I ever get a CETME or HK91, I've got some Cavim brass I'll use, and then discard if too badly fluted.
For .30-06, it's Lake City or Federal.
For 8mm Mauser, S&B is perfect, with a mil-spec thickness suited for European-level loads.
For .303 British, I also like the S&B brass. Heck, the S&B ammo is top-notch for the rifle, too!
For .45-70, I like Winchester, PMC, or Starline. BP loads, it's vintage balloon-head Rem-UMC.
For 7.5x55 Schmidt-Rubin, it's Norma.
For 6.5x55 Swedish Mauser, I also use Norma.
For my 6.5-06, I use 7x64 Brenneke brass, made by RWS or Norma.
For .223 Remington, I've taken a real shine to the Norinco brass. No primer crimp, and actually quite consistent. Wish I could find more of it!
For .44 Special, it's Starline.
For .45 ACP, anything but A-Merc. Bent too many decapping pins on that stuff!
For .357 Magnum Desert Eagle Ohmygawd 1600+ fps loads, Winchester Nickle-plated.
For 7.62x25 Tokarev/CZ-52, I use Starline, but have a bunch of S&B ready to go.
