The 338 Fed isn't going to win a longer range math contest, especially not comparing a TTSX to an ELD-X. It's a fatter bullet. But I know from experience the fatter 338 makes things very dead and using a CDS and a rangefinder I could care less about a little difference in drop. If shooting beyond 400-500 yds was what I was planning for I wouldn't get the 338. Since everything I've shot has been at shorter distances it works well for me.
