I'm interested in this answer too. I havent been able to find any of the 162 ELDX's, but 162 SST's are available. the reviews said that the 162SST was a decent elk projectile, but that was a surprise to me (and not sure I believe it yet).
what I can tell you is that the 162 SST's group very well in my 280AI which is pretty comparable to the 7SAUM.
if I had ELDX's and they grouped well, thats what I'd likely use, fwiw.
all that to say..... following.....
