I have a Uberti chambered in .44 special and am looking into a mould for this style bullet. So far I've been using a commercially cast .430, 215 grain. Good results but I'm just getting my feet wet. I'm going to be shooting with BP only so of course amount of lube is a concern. I like Mako's idea because it has one inside lube groove and one outside with a crimping groove to give the look of the heel based bullet. Going overboard, maybe but it's fun. I'm wanting to try something like this out because I want a cartridge that gets "close" to the original Henry. I realize that it was a rim fire and the other specs are off, but of all the chamberings available for the replica Henry rifle the .44 special gets me a little closer to my interest. That's the fun!
