Since I don't have the cases here to measure, could one of our experts please give me the case volumes of the 300 Win. Mag, 300 Wthb. Mag, and the 300 Win Short Mag. Thanks in advance......................

  Pore through the back issues of Hunting, Guns & Ammo, etc. for the articles on those calibers; they will mention case capacities and compare them to each other in almost every one. Or look at the SAAMI website for the spec drawings-you can figure case volumes with GEOMETRY. Don't have any use for arcane info like that personally; I just shoot them & go with the biggest blast!

  While this does not answer your question, Ken Howell's great book _Designing and Forming Custom Cartridges_ has been reprinted and is one of the best sources for the experimenter. He lists the volume of twenty .300 cartridges. His volumes, though are the case exterior volume rather than the case capacity. The case weights are listed and the capacity can be derived.
  The .300 Win Mag displaces 116 grains of water.
  The .300 H&H 122gr. H?O.
  The .300 Weatherby 133 gr. H?O.
  The .300 Kong 175 gr. H?O.
  The short mag is more recent than the book, and is not listed.
  (Sorry, I haven't learned how to type the subscript 2.)
  Perhaps this will give a hint of the relative differences of the cartridges's capacities.
  Cheers from Grayest California,
