So that settles it on the 350 TSX. I never knew they existed until I went to a large emporium where I do most of my shopping - was curious about them.
I do a lot of correspondence with a fellow who lived in Alaska for many years and had shot all big game there several times over. And he owns a pile of big bores. His favorites are .375s, including the H&H. He recommended (as I was scrounging for bullets and found a source for the TSXs) the 270, before I went shopping. So, thanks to all, and the 270 TSX is the consensus.
This is not my first .375 H&H. I've owned three others in the past.
Thanks again.
