according to beartooths permanent wound channel calculator a bullet with a .430 meplat (what it is with a wadcutter) striking at 1,200 fps would have a wound channel of 1.29" and should be good for elk and moose.
A true WFN nose profile is about as big as practical. Wadcutters just have too much frontal area that inhibits their ability to penetrate. Remember their original function was to cut a clean hole through paper. A lot a R&D went into LBT's bullet designs. I would suggest picking up a copy of Veral Smith's book as it goes deeply into bullet design and is very educational.
