Dixie Slugs has now added the Original Dixie Tusker – 12 ga. – 3” Mag. to their line of specialized ammunition. The Tusker is .727” diameter, which is the groove diameter of the popular Hastings rifled barrel, as well as others. The weight is 600 grs. and makes it one of the heaviest on the market for rifled barrels. The truncated cone has a .500” meplat. The ballistic coefficient is .145. The base is hollow with thick skirts and it is heat treated to a hardness of 30+ bhn. The alloy used in this hand cast slug/bullet is 94% lead, 3% antimony, and 3% tin. There is an Alox wash for lubrication. It is loaded in new primed 12 ga 3” Cheddite hulls. The average muzzle velocity from a 20” rifled barrel is 1550’/”. Barrels longer than 20” will have a little more velocity.
Dixie Tusker External Ballistics
First of all, it should be understood that the Dixie Tusker is not designed to replace rifles for extended hunting distances. It is designed to give the hunter/shooter a very powerful load to use in dense cover for large and/or dangerous game. Accuracy depends on the type, and design, of the firearm it is used in. In Switch-Barrel guns with a low powered scope, 4”-3 shot groups at 100 yards in the norm. When fired in solid action guns, like the NEF Ultra and bolt actions, the accuracy will equal any other big bore rifle.
