I've been sorting through my shotshell collection and came across a bunch of heavy #2 12ga rounds, some 2.75's with 1 1/2oz of shot and some 3" with 1 7/8oz of shot.
I figured these for obsolete goose loads but remington still offers these loads with lead pellets and gets $30 & $37 a box for them so someone must still be using them for something.
The only hunter I know that uses lead #2's uses them for shooting midget antelope in Africa.
