My Series 70 Combat Commander just LOVES the PMC-El Dorado Starfire JHP. Over 300 rounds of them through the gun w/o a single hiccup.
Recovered specimens from pumpkins and wet phonebooks are pretty impressive.
The 200-grain JHP by Speer handloads are also used, and work very well. Expansion from that monster is just incredible to behold.
There are three things in this life that make me smile ear to ear -- Mastiffs, Magnums, and Merlots. Don't try to take any of them from me.
