I am sure it was either a Sierra or Hornady bullet, so my load data would be of limited use for you.

I did a Quickload table with your bullet so you can compare potential velocities and fill percentages of different powders.

Code:
Cartridge          : .30 Herrett












Bullet             : .308, 110, Nosler VarMag 34057












Useable Case Capaci: 31.165 grain H2O = 2.023 cm³












Cartridge O.A.L. L6: 2.320 inch = 58.93 mm












Seating depth      :  .204 inch












Barrel Length      : 14.0 inch = 355.6 mm


























C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested












loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand












that all of the listed powders can be unsuitable for the given combination of cartridge, bullet












and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.

Just wondering….why run that table at such a low pressure? Seems like 40-45000 psi is closer to normal max contender pressures?? Do you agree?
