Campro is working on a .50 bullet for Desert eagle and 500S&W. Probably available this spring.
Awesome, I was hoping they'd come out with a .500" pistol bullet. The availability of the Berry's 300grain is so hit or miss, and there just aren't really any other reasonable plinking options. Half the fun with a DE is mag dumping the thing, and paying a dollar+ per bullet kind of takes the fun out of that, lol.
