I've used the older Barnes 200X in 338WM on Plains Game, the 210 XBT in a 340Wby for Plains Game. I also killed a cow elk with the 185 XLC from a 338 WM. We also slew dozens of Plains Game with the 180XBT/300WM. I liked the 200x in a 35 Whelen AI I shot at 2970fps ( thats 338 WM territory) Really, for elk, whichever one you want to use in your 338 Pard! smile I shot the 160 TTSX to 3000+ fps from a little 338 Federal, thats 7mm Rem Mag territory! Have a ball man! smile
