Hornady interlock- dam near as good a Partition. In years of working a gun counter, can never remember hearing a compliant about them for deer or elk, and they were our most popular bullet.
I can complain about them. We had mixed results back in the 70s/80s with 180s from two '06s. A small percentage performed correctly, the rest either disintegrated or penciled through. We switched to head shots to reduce the amount of tracking needed. Others' experiences vary I'm sure, but that's how it worked **for us**. Sierras were no better but they seemed to be more accurate. I switched to Speer Hot Cores and my problems ended, my father stuck with Hornady and Sierra and his persisted.
