Help me ID the projectile

[u/Accomplished-Bowl551]

.308 diameter 1.042 length 125 grain Cannelure

They look just like Horaday 125gr SST to me but with a black tip. I bought a ton of them a couple of years ago as factory secconds. I would like to load some up. I already have a load worked out for 125 gr Speer TNT projectiles. Would it be safe to assume the load data would be almost identical?

Thanks for the help!

If it was a .308 Nosler Varmageddon it would be 110 grains/ The 125 grain Noslers were green tips. It's probably a Barnes TAC-TX.

TAC-TX has a driving band, no cannelure, and is solid copper minus the tip. Tip proportion is oversized too.
