In the 338-06 heavy bullets are pretty slow compared to the 338 WM. I’m thinking the 225 is about the heaviest I‘d want to use, saving 250’s for the 338 WM.

And bullet length is a consideration with case capacity. The heavier monos are pretty long. In fact if you look at the 160 TTSX, it’s almost as long as the 210 NPT. If the 180 NAB shoots as good as I think it will, it could be a player. Right now, 160 TTSX and 210 NPT are top contenders.
