The 338-06 is very close to the well-proven 35 Whelan (also based on 30-06 case) in terms of ballistics. More people seem to be gravitating to the 338-06 because of better bullet selection. You shouldn't need a 28" barrel unless you are looking for marginal increased velocity. I would think 24"-26" is all you need.
If you can get the TSX to shoot well through your barrel, they are absolutely leathal. I love 'em, but they don't always give me the accuracy I need in many rifles. A fantastic elk round.
