Never saw a need for sabot slugs. Forster slugs in 20 or 12 was a one shot done deal on hogs or deer. Longest shot I ever took was with the 20 at about 75 yards on a hog. Boom-flop, mostly jello in the boiler room.
The same in a .410 works well also but at short range, say inside 25 yards, tend to make a wicked shallow crater.
