I've found the discussion interesting but just a bit off topic. I restricted my initial examination to 416 Taylor and 404 Dakota for a variety of reasons, most having to do with the basic gun platform I was working with: Mark X Whitworth action, Blackburn bottom metal (+1 to fit 458 Win Mag) and McMillan CZ Express stock. This morning I dummied up some cases in 404 Dakota and 416 Taylor for a trial fit in the magazine box. 4 Taylor cases are a near perfect fit. 4 Dakota cases are too big for the magazine box in both width and depth. Based on that I'm restricted to a 458 Win Mag or one of its derivatives such as the 416 Taylor or 425 Express.

I think Daryl's comments about limited bullet choice and cost of components is telling, as is the fact that some of the more renowned ammo suppliers like A-Square load the Taylor but not the Dakota. Since I'm an experienced reloader, practice ammo is not the issue, but I have a real fondness for A-Squares Triad loads when commercial ammo is required.

Thanks for everyones' input, but 416 Taylor seems to get the nod for a host of reasons. Thanks.
