I am sure this has been discussed, but who has tried the new magnum pellets?

On one of my ML's, disc elite, I cannot beat the accuracy of pellets. I shoot 3 50gr equiv 777 pellets with a 250gr Barnes expander at over 2000fps. And I get 1.5MOA-2MOA at 100 yards. I have tried everything to get rid of the pellets. I have tried 100gr-130gr of FFg loose 777, pyrodex, pyrodex select, and 5 or 6 other sabots with and without subbases. Best I can get is 2.0-3.0MOA. I hate using pellets. I even tried a fancy breach plug from knight that lights at the front of the charge. It helped.

So if you can't beat em join em. So I figured I might as well pick up another pack of pellets. And saw these new mag pellets.
