6.5-284 Norma brass weight

[Jastreb]

Hi

Got some Norma 6.5-284 brass that i have been weigh sorting. It turns out that weight difference is as much as .12gr in some cases.
How much of weight difference is acceptable???

Depends on the level of accuracy you want. For benchrest or F-Class competition, you would probably want groups of cases that would weigh within about 0.3 grain of each other. If you search this forum, you will find posts that discuss the sometimes poor relationship between case weight and case internal volume but weight sorting them is a good place to start.
