I bought a Ruger 77 in 7mm RM with the idea of making it a 358 Norma Mag or a larger caliber. First thing, I changed out the stock to a B&C stock, as the Ruger's stock wasn't right for me and I think the barrel is too light on that 77 for a rebore that big, so a new barrel would be in order. A 416 Tayler would be one of the cartridges I'd consider. Another would be a 375-338 or rather a 338 WM necked up to 375. I have never had a 700 extractor fail, but all of my bigger bore cartridges 338 Win and up now have claw extractors, just because of all the whining I read about extractors.
I have two other 7mm RM's on 700 actions and I really don't need a third 7mm RM all that much. For me, I've come to realize I have more larger caliber rifles than I'll probably ever use.
Back to your situtation: I think a 416 Taylor would be a hoot. Go for it.
