I have the 230's moving 3035 and from what I have read I could get the 300g going 2800 or so out of the edge.. I will be using a Brux 27" barrel. Just looking for some thoughts. I do have a new 8lbs of Retumbo which I use for the 300 and know the 338 seems to do best with H1000, which is hard to come buy these days.
If your wanting to go after mature elk at ranges past 1/2 mile, the 338 will be more authoritative on impact. Ballistically, I would say it would be very hard to say one would be better then the other if your using the 230 gr OTM in the 300 RUM.
The 338 will have a slightly longer barrel life if both were cared for the same way.
H1000 is great in the 338 Edge but I actually prefer Retumbo. A bit higher load densities, same velocity with a bit lower pressure for longer brass life.
Again, in the end, it comes down to what game will be hunted and at what range, deer and elk inside 1/2 mile, take your pick, elk past 800 yards and especially out to 1000 yards and beyond, go 338.
