I have never made a 416 Ruger, but when I look at the case I believe it may be as good or better then the Taylor, for all the same reasons. The 458 brass you make the Taylor from is likely to be easier to get and way cheaper then the 416 Ruger brass, but with no hands-on knowledge, I can't say for sure.

Anyone out there have any feedback for me on the Ruger?

So maybe I should modify my earlier statement that "in my opinion the 416 Taylor is the best of the bunch" to "the 416 Taylor or 416 Ruger are probably the 2 best of the lot".

Keep in mind, I am speaking from the standpoint of building rifles. Not from buying a factory available rifle. If I were to buy one I'd probably just buy a 416 Remington in a Winchester, CZ or a Ruger and be done with it.
