For the roar just use the heavst bullet you can find
Cast from pure lead if you feel inclined you could drill a hole into the Center of the nose of each bullet to make a hollow point
Load to somewhere under 1200 fps and go hunting you don’t need to worry too much about accuracy as roar hunting is normally close
For lobbing rounds out to distance you really need to get into weighing your projectiles for consistency
But id still stick to pure lead unless you’re really wanting to push the speed up but I wouldn’t suggest it I have found cast bullets way more accurate if kept slower
