I hunt where using sabot-encased bullets for muzzleloader hunting is illegal. This isn't a problem now that I use PowerBelt bullets. Because they are .001 inch under bore, and the pliable plastic base is slightly over bore, the assembly loads easily and fits tightly over the powder. That, combined with a gas seal that eliminates blowby, yields consistent pressures and high velocities. Copper cladding on some PowerBelts reduces friction in the bore, further increasing velocity. The base also protects the tail of the bullet from flame cutting. Performance on game is awesome. In .45, .50, and .54 calibers. $12¿¿¿$19; 800-376-4010; powerbeltbullets.com -B.R.
