I hear a lot about stout cast-bullets , it would seem you could get a lot more powder behind a jacked bullet?
One of the advantages of the cast bullets is that they can be safely driven faster than a jacketed bullet. I'm sure a jacketed 300 grain HP will kill, but the large meplat on the LBT type bullets will also destroy a lot of tissue. I like the 300 grain LFNGC in my 45 Colt at about 1200 fps. But I have not shot any large game with it yet. Wouldn't hesitate to use it on anything in NA.
