Many times, the .44 caliber bullets will shoot well in a .429-.430 diameter sabot. All you can do is try them. After all I shoot a .430 300 grain XTP in a crushed rib sabot in mine. The XTP will shoot well in handguns also. I used to shoot a Hollow Point in my Red Hawk .44 caliber but they put too big a hole in the deer so I went to a solid tip flat point.
