Norma and Nozler has the reputation of quality cases.
Since the days are short, I measured the variation in neck wall thickness of four different brands of 300 H & H cases.
5 cases were measured for each brand.
Measurements were taken using a tube micrometer on 4 quadrants of each case neck.
Nozler had the least variation with every case neck having a range in neck thickness <= 0.0004"
Norma was next with every case have a range in neck thickness <= 0.006"
Federal cases all exceeded 0.0006" variation, with the highest 0.0009"
Hornady were most variable, with all necks exceeding .0006 and highest 0.0012" range in case neck thickness.
Federal and Hornady had consistently thicker neck walls (mean thickness = 0.0121, 0.0125")
Nozler and Norma had thinner neck walls (mean thickness = 0.0115, 0.0117")
