Don't have any direct experience with the 165 or 180 but my 06 likes 55gr of H4350 with the 168 TTSXs. Don't remember the exact velocity but it was just above 2800fps. Groups were right at .5 MOA
30-06 165 or 168 ttsx Which ever shoots better in your gun. This combo has been very accurate in three rifles I have tried it in.
