Congrats Zee on your accomplishment! Before you begin to question the load's accuracy, or perhaps your aim, consider the time of flight for that slug versus how much a deer can move in that same amount of time. Just one step could easily move them 3 to 6 inches. That barrel looks like it was made by Krupp's for the German army, awesome. Looking forward to the science part. If it is anything like my 500 S&W kill this year with a 440 WFN going 1060fps, you won't have any blood shot meat. That's a pretty bullet, I need to call Matt and get some.
