Have to agree, that 165 TTSX might be a better option than a 200 gr anything in a 30-06 if you plan to stretch the range out. Not knockin' the 200 gr partition but it needs velocity to expand properly, and as such it does start to lose a hair of it's potential sooner than you might like. It'll penetrate anything you want to launch it at for a reasonable distance, but on lighter game you might get pass-throughs without much expansion, especially as the distance-to-target increases & velocity drops. That 200 is really at its best in the bigger cases, say 300 Winmag and up...200 FPS doesn't sound like all that much but it sure can make a difference on a less-than-perfect shot when the wind is a factor, too.
I have a buddy who has used the 165 TTSX to take western game with his 30-06...one of those one-rifle kind of guys, but he doesn't miss with it either. Per his reports that combo has done him justice out 400+ on deer and cow elk. I've only witnessed him take deer with it, but he claims it to be a good all-arounder for anything from antelope to elk.
Of course every rifle is a bit different, but you oughtta be able to get some reasonable speed and accuracy if you power that TTSX with somewhere in the range of 57-60 grains of Ramshot Hunter. That powder and charge weight has done pretty well for me in the '06 with several different 165-168 gr pills, including several of the high-BC types.
