308 Winchester / Reloading:
Written by: Kim Lockhart, Copyright.

308 Winchester Centerfire Rifle Cartridge:
 The popular 308 Winchester centerfire rifle cartridge is a commercial, rimless, bottleneck cartridge case design that is loaded commercially (factory produced ammunition) or reloaded by individual handloaders with various combinations of primer, powder and .308" diameter bullets. Handloaders can calculate the kinetic energies of their handloads with the use of these formulas.

308 Winchester Reloading Specifications:

Bullet Diameter - .308".
Primer Size - Large Rifle / .210" Diameter.
Case Neck Diameter - .343".
Case Shoulder Diameter - .454".
Case Base Diameter - .471".
Case Rim Diameter - .473".
Minimum Case Length - 2.005" / Trimmed.
Maximum Case Length - 2.015" / Stretched.
Minimum Cartridge Overall Loaded Length - 2.490".
Maximum Cartridge Overall Loaded Length - 2.810".

308 Winchester Reloading Data:
 For the Deer, Elk or Moose hunter hand-loading or reloading his or her own 308 Winchester ammunition, Western Powders, Accurate 2520 rifle powder does an impressive job of launching 150 grain .308" diameter bullets at high velocity. Accurates online reloading data shows that a 150 grain .308" diameter Hornady SST bullet using 44.5 grains of Accurate 2520 powder can be driven to a velocity of 2,770 feet per second loaded at a maximum cartridge overall length of 2.735" in the 308 Winchester. This load does not top out until the 150 grain bullet is at 3,006 feet per second at a chamber pressure of 61,771 PSI. For the 150 grain bullet reload if you sighted your 308 Winchester hunting rifle in dead on at 220 yards it would only be 2 inches high at 150 yards and only 3.4 inches low at 275 yards which would be an excellent deer, elk and moose load.
