I missed the make of your muzzleloader. As long as you buy the pre-packaged bullet/sabot combination you will get matching items. The problem with that is some of the load much harder then others do. The only way to find which one works in your rifle is if someone other then you has the same rifle and has tried them, it will give you a starting point. Your still going to have to buy different sabots and try them with different projectiles.....
