I’ve never used either of those exact bullets but have used ( or seen used) a considerable number of .308 168 and 180TSX and 8mm 200 TSX on all sorts of game in Africa, including big bull eland. My dad shot a bull with 180 tsx out of his 300 Weatherby and I shot a bull with 8 rem mag with a 200tsx at about 45 yards. Both shoulder shots and both bulls were down very quickly. Bullets looked like advertising pix.
