I've shot both bullets in my 284 at around 2800fps..
I've not done a side by side comparison but they both shoot great..
Scenars don't blow up if pushed like the ELDM'S can/do.
I've not lost one at 2800fps but I know some who have going over 2850fps..
My saum blows them up at 2950fps.
Since my last blow up I've put 700 or more bergers through my saum without an issue..
