I will try the h4831 sc first at 57 gr and go from there.I know the book says 58 grs is max and yet I see people posting 59 and even 60.I have only done that a couple of times with ballistic tips and have gotten a few split necks.I switched from the 150 gr BT to the Accubond mainly becuz of the new law regarding being able to cross a fence in order to retrieve game.I have never lost anything after being shot with the BT,but they can go 100 or so yards,with the Accond they go about 2 feet-2 feet straight to the ground.Another reason I switched was for those times when I run across a good sized hog.No problem there either.I just cant believe there is no "published data" for the round.
