Not the ELD-X, but I’ve seen the 180 ELD-M impact a bull moose on a frontal shot at ~30 m. The bullet was launched at 2930 fps at the muzzle. Impact was above the brisket, and the bullet penetrated about 4’ of moose before exiting at the rear of the rib cage. Moderate wound channel and the bull had 4 hooves in the air about as fast as I could blink after the shot. Don’t see that all that often with moose. I was quite impressed with both the bull’s reaction and the bullet performance.
