I like the 350 grain TSX/TTSX 93 grain of 2000MR give 2715 FOS out of my 416 Rem. I don't see the need for 400 grain mono bullets in 416
You're not the only one who likes the 350 TSX. I've seen that one mentioned a number of times.

My 416 Remington is getting fed 350gr TSX's. Likes them better than the TTSX's. Rifle hated the Speers, and looking for some 350gr A-Frame's for deer should I be so inclined.
Got 500 plus of the TSX's and should be set for a long time. I will shoot at least 400 of them getting ready for the next buffalo trip. That is, when I decide to go back.
