Yeah they're Hornady's. I have some and could only sell them to someone who knows nothing about "solids" for dangerous game. Hornady hasn't made them for some time for a good reason.. . . . They didn't do the job intended, but bent when hitting big elephant bones, or sheared, or . . . . whatever. The only plan I have for mine is for practice shooting.
Hornady's latest has a decent reputation: the "soft" has a flat tip with an exposed hardened lead core that's bonded to a steel jacket with a copper coating. The solid is the reverse. The expanding bullet is called DGX (Dangerous Game Expanding, and the solid is called DGS (Dangerous Game Solid).
Depending on how many you have, $50 wouldn't be too much several years ago, but today you'd be lucky to get $20. No one would buy them for serious work in Africa on DG, other than for relatively cheap practice shooting before a safari.
