But the bullets in the sabot need to be soft, pure lead soft.
If too hard, the MZ does not have the velocity of smokeless ammo and will not humanely kill an animal. The bullet will just punch through and not expand.
Also, I use the regular Harvester Crushed Rib sabot in .451" and a pure lead SWC in .454" and it works great. But my bullet is only 255gr. Larger bullets, over 300gr, might need the .454" sabot.
