Correct, but Nosler preps and weight sorts, so at least you are getting something out of it for the cheaper common cartridges.
If it's Nosler and it's $50-$60/50 odds are pretty good it's some decent US brass that has been weight sorted and prepped, vs Win/Rem/Fed/Hornady that you would have to prep, and discard probably 20% due to weight variations.
I only buy Nosler in belted mags...7mm Rem and 257Wby, I can confirm they are made by Norma based on weight (as in they weigh the same as Norma brass) and the drilled (not punched) flash holes. Now they are $100/50 and not cheap, but they are quality brass casings that are a bit cheaper then having Norma/Weatherby stamps on them for identical brass.
