Why do we have heavy lead slugs and sabots featuring 300 grain pistol bullets with 30 pounds of recoil? I know there were some old tech issues in the beginning but...

Why not a 150 grain 30-30 class bullet in the sabot and faster and flatter?

Now with the straight wall laws the sabots are probably obsolete but I wonder why no one tried this?
