Hey Okie48, you're right to some extent. You can use a .50 caliber .451/.452sabot to shoot any .451 or .452 caliber bullet, butbullet selection is important.

For example, if you shoot .452 200grain round nose full metal jacket or cast lead bullets made for the .45 ACP they will probably not be very accurate an definately would not be suitable fordeer size game. OK for short range plinking and varmints though (but you'd probably be better off with a patched round ball).

The reason you see Hornady XTPs marketed with sabots for MLs is that they are appropriate deer bullets. Nosler partitions are excellent. Speer Gold Dots, either 250 or 300 grains, are fine also.
