BigTime6656,
Indiana SmokePole gave excellent advice in his post, and I would like to add to it to explan a few things. What your gun "likes" means "most accurate" in your MLer, shooting your powder, using the sabots you intend to use. Most folks when they are selecting a bullet will try the supplied sabot of the bullet maker. That is OK if it works---shoots accurately and is OK to load. However, there are several on this forum that recommend you purchase a package of MMP HPH12, 24 and 3 petal ez-glides from MMPSabots.com and a package of Harvester Crushed rib.Take your breech plug out. Take each of the sabots with each of the bullets and see how they load in your gun with a barrel that has been swabbed, in this way you match up the bullet with the proper sabot. Keep notes of how various combinations feel going down the barrel (ie very loose, little pressure required to load; had to pund the sabot and bullet down the bore with a rubber hammeretc). You then shoot the combo in your gun seeing if it groups well. Once you find a sabot to fit your bore with the bulet you want to shoot then your ready to go. 3" group at 100 yards is the norm for a good hunting group. Many here get 2" and some 1 and 1.5" with their rifles and their bullets. Best Wishes on bullet selection.
