Could I use any pistol bullet I wanted paired with a .50 cal sabot that it fit into? Thanks again.
Short asnwer. Probably!
As long as the sabot is designed for the caliber of bullet you intend on using, then yes. You would have to buy 50cal sabots made for 45cal bullets (451-.452 but not .458) or 50cal sabots made for 44cal bullets.
As far as the bullet not sticking out past the petals, not so much. Pistol bullets were selected because of the low impact velocity of the projectile being fired from MLs. Rifle bullets almost always will have much thicker jackets requiring them to be driven much faster in order to initiate expansion.
