I have to agree with above, I use the sabots in my 50 with .429 and .452 bullets, depending on the sabots that I get. I usually use my own cast bullets of relatively soft lead and they give a flatter trajectory than any .50 bullet out there for 100 to 200yds. 250 to 280gr cast bullets can drop any game in our area. I've dropped deer at 155yds with a 250gr and it was a bang flop so I'm happy. I can do the same with my 54 and 320gr cast bore size bullets, but with a much greater hold over and more punishment to the shoulder. Less trauma(to me), less weight to carry and flatter trajectory, I use the sabots much more for hunting.
