I'll just say its interesting to me how people arrive at the conclusions they do. Nearly every "long range" bullet has a tapered jacket to make the tip more frangible and the base tougher. Including eldx.
You have a point to a degree.
Even the Hornady SST & Interlock, Nosler Accubond and Ballistic Tip.
Although none of those are typically what one would choose for shooting long range.
They all behave differently in their terminal performance.
Some expand more rapidly than others.
My friends and I have recovered a lot of SST, Interlock, ELD bullets from deer.
In the 40 years of deer hunting, I have yet to recover a Ballistic Tip.
The Hornady's have all expanded rapidly, doing more shallow damage.
The Ballistic Tip doesn't open quite as fast, and does more damage to the vitals, giving a pass through.
Heck, even the Berger VLD seems to penetrate deeper before rapidly expanding. Making Jello of the vitals, and dumping all it's energy.
I usually find the jacket under the offside hide. But have yet to see a deer make it more than 20 yards.
