RE: Recommended premium brass
When did Norma brass become premium brass, and a cut above the others?????? I've reloaded many thousands of rounds of Norma brass over the years, and i've never really liked it all that much. To me it's too soft, it's NOT top of the line in my book!!
All WBY brass was made by Norma, (it may still be??????) yes it held more powder, but how many times could you reload it???? WBY brass is soft too too!
I've had pretty good luck with Remington, Federal, and also Winchester brass. I also have quite a bit of RWS brass, and it's good stuff too. I've also worked a LOT with BELL brass, as i designed a few cartridges useing that case, and i mfg'd and sold the ammo for it.
For me, what is most important is to make sure all your "lots" of brass are the same and don't mix types or brands. If your real picky, deprime, and clean your brass, and weigh each of them. Then put the different weights in different boxes, and use them as groups.
Hope this helps,
