These shots were fired at 50yds bench rest, 20ga 870 rifled barrel, the rounds were a 44 cal bullet in a SPW in a Hornaday hull on top of 19 gr of WSF.
I do have a question, is there a mold out there that I can cast and load like a Lee keyway, it seems to me that i read somewhere that a .58cal, might work, this is for 20ga. Thanks
