To get low pressure, one needs a larger case than necessary, which requires a larger, subsequently heavier, more expensive action with a longer throw - normally.
In concert with the lower pressure comes more recoil energy, although it is usual to be at a slightly lower recoil speed (due primatily to lower pressure).
Since you are dealing with a modern rifle, there is no need for low pressure ctgs. today, if a standard ctg. fills the gap - however, there is always a "need" if one wants one regardless.
More costly dies & brass, a quite narrow and expensive supply bullets are also requisite for the .404 Dakota, .425 Express or .404 Jeffery.
However, for a wildcatter, sometimes one just WANTS something different.
The .416" bullet of course, has a higher SD and BC than the .425" versions, which, with modern Premium deep penetrating bullets, is not a valid argument - depending on availability, of course.
With use of today's powders, low pressure is a non-argument and has negatives attached, like size, recoil, cost.
The more it costs to shoot, the less it will get shot.
Agree totally with this post..
The Taylor I believe is very similar to the .416 Remington in terms of FPS and Energy..the latter of which I have used on 4 hunts in Africa in a wide variety of temps...have not had one single incident to date..plan to go back in the not too distant future..will probably be take one of the 3 I have in that caliber once again..recently added the "new" version of the safari grade Winchester..having it fitted to a custom wood stock as I did NOT like the factory one even a little bit..to me it felt like a club...
ON my reloads for the .416 shooting 400 gr bullets using RL-15.---I am getting in excess of 2400 fps per my chrono..with both Barnes solids and Swift A-Frames...
Having said all that, actually have been looking around for an action to build a .404 Jeffrey..have always wanted one of those as well..and as stated above, "need" has nothing to do with it..
