First is a long pointed slug with locked on base, It goes to target with base,can work smoothbore.
Second is picture of Hexolit sabot base slug with petals expanded, sure would make bad wound.
Third shows a variety of Gualandi slugs you can get for reloading, and we're finding that these locked base slugs, Brenekke/USS style slugs, are giving good accuracy in smooth barrels which can save when doing heavy barrels.Weights shown in grams, get our weights in grains multiply by 15.4..Ed
