Re: 404 Jeffrey Load Data for 416 Rem. Mag

Yes, I agree with the bullet needing the extra velocity for proper expansion. But, I mainly just wanted some slightly reduced loads to practice with, but still have a good hunting load as well. The Jeffery with it's 400 grain bullet at 2150 pretty much made a great name for itself at that power level. Seems it should do just fine today. My Sako AV only weighs 8lbs, so it's quite lively with the full power loads, to say the least.
Really what you want is reduced power loads not ".404 Jeffery" loads. The .404 loads at 400 grs/2,150 fps are the historical powered loads. Using modern powders the velocity achieved can be significantly higher. Up to, approaching 2,400 fps.

JJDonnelly lists the case capacity of the .404 Jeffery (.520" shoulder) Rimless as being 115gr. water.
The .416 Rigby is listed at 132.56gr. and the WTBY should be about the same as the .416/378, at 140.8gr. water. The .416 Remington should be about 108gr., same as the .416 Barnes Supreme.
The .416 Howell, using the .404 case necked down with a shoulder diameter of .515" and OAL of 2.55", is listed at 100.78gr.
As Daryl points out here, the case capacity of the .404 is marginally greater than the .416 Rem Mag.
Also being slightly larger in calibre ie .423 than a .416 all other things if equal, the .416 would develop greater pressure from the same powder loading.
