This is getting confusing:

Falcon - the Cabela link takes you to the MMP sabots. While the opening picture is of a black sabot, were you to order the 50 cal .429 sabot, it would be green and longer than the Hornady green sabot.

Lemoyne - the link to Harvester offers the crushed rib for a 44 caliber bullet but not the high pressure short sabot for 44 caliber.
