Last season I personally Harvested 7 deer with my own cast , .452, 333 gr Hard cast Boolit , my mold is identical to the 45 cal version of Harvesters hard cast. Water dropped WW alloy is what I use.
The 430 version is what is know as a WFN, the .452 version is a LFN, I believe the basically have the same dia. Meplat. I could actually measure some .430 I have.
The designer of the Boolit recommends a MV of 1500 FPS for quickest Kills. That works well for my family and I.
