My preference is Lapua, Norma and Winchester in that order. I recently bought some Nosler brass which comes prepped and weight sorted to +/- .5 grs. I haven't had a chance to use it yet, but I measured neck thickness on a few cases and they were very consistent, so I'm anxious to give it a try.

I've tried RWS and didn't particularly like this brand. I haven't used Remington in a few years and have no desire to.
