I just received the Lee clone of the hollow based, 405 grain 1873 government boolit. Interesting mold with two features that make me go "hmmm. . ." The first is the relatively small hollow base pin, which will leave a fairly sturdy skirt on the rear. The second is the three ginormous lube grooves.
I'm thinking between the hollow base and a large quantity of a modern lube (Ben's Red in my case), this thing can be driven pretty hard. As I say, stay tuned.
