Are you talking .50 caliber guns piero? You can shoot any .451/.452 pistol bullet from 180 grains to 300 grains in a 50/45 sabot, whether the bullet is jacketed or lead or copper or steel. Lead bullets from pure soft lead to hard wheel weights are OK, though it's said that pure soft lead shot at high velocity will sometimes grow "ears" through the slits in the sabot. Regardless, there's no safety concerns at all with any of them. You can shoot .458 bullets made for the 45-70 in 250 grain to 500 grain in MMP orange sabots made for those bullets with no concern. In some guns with loose bores you can load the .458 bullets in 50/45 crush rib sabots.
