I've used the 168 grain TTSX in the .30-06 and the 150 grain in the .308. My son and I killed a bunch of animals with them last fall in Mozambique, including Sable, Waterbuck, Nyala, Kudu and Reedbuck. We had great performance from both bullets. I've also used the 168 grain TTSX on elk and it worked well. I shot a 5 point bull and it only went about 30 yards.
If I were to use the 150 grain TTSX in a 30-06 I would start with Ramshot Big Game. In the .308 I use TAC.
