290 T-EZ for our .50 Bighorns. Deadly, deadly, deadly. We've killed about 15 animals over the last 6 years with them. All bullets either recovered in the far side hide, or exited after leaving a baseball-sized wound channel. The only (minor) downside is that they tend to tumble around in the critter. My buddy shot a broadside deer right in the boiler room, and recovered the bullet from the far side hindquarter. As others have noted, the wound channel from those petals is impressive.
