the eld x isn't made for short range high speed impacts { 3000 + fps} its also not designed for shooting through bone you recovered the deer obviously the bullet did its job the deer died5 Year old thread but a good topic since 3 days ago I shot a 7x7 whitetail at roughly 240yds with a 200 grain ELDX and it Blew the F up and no exit.
It only went 35 yards ran slow but like it had not been hit. The last 5yds it jumped into a cedar wind break and for 40 minutes I did not know if it was still going.
But it was dead inside 5 yards of the Cedars. Still causes stress LOL a 200 grain bullet at 240yds ***????
I've killed 45+ elk and whitetails & 15 black bears with a 6.5cm 143 eld x @2880 fps from 60 yards out to 550 never had one blow up never needed a second shot.
the eld x works best at impact velocities around 2600 or below they are a long range bullet they are not designed for short 0-300 yards} range high speed. impact or shooting through shoulders call hornady and they will clearly tell you as much .
