sabots are made to do a number of jobs with a number of different projectiles. They can handle .400, .429-.430, .451-.452, and .457-.458 in just the .50 caliber rifle alone. Then they are also made according to the kind of powder charge you want to shoot. There are standard sabots and high pressure sabots for those that like to push the powder to the. They also come in many thicknesses.

Harvester makes a crushed rib sabot that I like, and is easy to load in most all rifles. They also make the standard and high pressure sabot. Not to mention the length of the petal on the sabot depending on the kind of powder you want to shoot.

MMP makes a number of different sabots for different companies. They make the Knight sabots and I think the Nosler as well, but would not swear to that. They do make the blue 10mm sabots such as those you find in the 200 grain shockwaves, and for those that like to shoot the 200 grain 10mm XTPs. Then the green sabots are the .430 caliber for the .44 caliber projectiles. The Black sabots are the .45 caliber that come in .452, and the orange sabots are for the .457 45 caliber for projectiles that you might shoot out of the 45/70 Government and some of the Nosler projectiles. MMP also makes a couple thicknesses of sabots. The HPH-12 is their standard sabot. The HPH-24 is the thin sabots. And they make some three petal for easy loading. Sabotloader is much more up on the sabot end of all of this..
