Speculation but, that leaves room for Hornady to introduce another bullet down the road....a bonded ELD-X type bullet. The ABLRs are not much (if any) better than the ELD-X in that regard. They are nowhere near as tough as the typical AB bullet by Nosler but of course that is by design.
I haven't been able to get my hands on any yet but, the new Federal TLR (or the Trophy Bonded Tip, just not as sleek) seem to be exactly what we're asking for in that regard....still expand at long range but hold together up close. On paper, this is about the "perfect bullet" IMO. Not as cheap to shoot as the ELDXs though.
