[QUOTE="Bowfishn, post: 1425618, member: 56875"] Not sure the H2O of Prime brass in the 6.5 CM, some say it's about the same as Norma or Nosler so I will use 52.7 gr H2O RL26 with 143 ELD-X Cartridge : 6.5 Creedmoor Hornady Bullet : .264, 143, Hornady ELD-X 2635 Useable Case Capaci: 46.718 grain H2O = 3.033 cm³ Cartridge O.A.L.
