Why does the 30 Nosler case dimension differ from the 26 and 28 Nosler case dimensions?

  • To prevent cross-caliber chambering (i.e. a 35 cal cartridge in a 33 cal chamber).
  • To accommodate longer bullet ogive lengths for larger calibers (30cal bullets have longer ogives than 6.5mm bullets do) while staying within 3.340” COAL.
  • To provide a respectable neck length for each caliber. The larger the caliber, the more neck length is needed for adequate neck tension.
