Bullets designed for revolver velocities can't be expected to hold together when pushed a lot faster. These days it's probably wiser to use bullets designed specifically for MLs or rifle bullets like the ones you bought. I've got some .458 sabots I acquired by buying Nosler BT ML bullets and removing the bullets for use in my .45/70. I'm going to try the sabots with Laser cast 350gr bullets in my Knight.
BTW, SPS has the Noslers on sale for $8.45 per 15. They're overruns, not blems. I bought a bunch.
If you can't get the orange .458 sabots, the Harvester Crush Ribs may work okay.
