I will add that if I did not want to shoot monobullets, I would also suggest the Nosler 210 Partition. The sierra 215sbt gets lots of good reviews too. No doubts a good 225 ( I don't call the SSTs an elk bullet, but hey, some do!) I can't see a 250gr unless you just want to go "Old School" and they are indeed a thumper up close in the dark timber! A lot depends on where/how you get a shot on them. I like the Monos as I have used them since '95 on my first Plains Game hunt, from a 35 Whelan AI, a 250X going 2550 ( very comparable to a 338Win with factory loaded 250s) I shot zebra, blue wildebeest, hartebeest, gemsbok and kudu with it, only recovered two lengthwise bullets , one each from the zebra/kudu. In the monos, I like the bigger caliber/yet fast speed of the lighter weights, than say, a 300Winmag with 180s. One thing is for very sure and certain...your 338 Winmag is a "Jim Dandy" elk round! Good luck to you, whatever you choose!
