"Failure" with 143 eldx at impact velocity of 2260 fps (260 yds) uphill broadside shot on 300 lb l black bear. I say failure only because similar to above, the bullet had surprisingly little penetration, yet did kill quickly.
Entry on upper left side ribs and bullet trapped in fat under opposite shoulder. Jacket and core separated completely and most of the core was inside the chest cavity. Bear ribs and shoulder muscle/fat aren't tough or particularly thick, so maybe 10-12" penetration at most for a bullet that is supposed to retain some lead core (crimped "x" ring).
I'm in no way complaining about how dead the bear was, just questioning use of ELDX on larger animals with quartering shots needing more penetration. Likely moving to 153 TMK in the future for a little more certainty on penetration.
