This bullet was designed for rifles chambered in .416 Rigby and similiar cartiridges. Our MTH line is machined out of lead free solid copper bar stock on a CNC lathe. These are a high BC, expanding bullet designed for hunting at all ranges. A unique feature of this bullet is our patented SealTite? band which is a band slightly larger than caliber diameter around the bullet which was designed to eliminate fliers by preventing gas blow-by. The SealTite? band also decreases copper fouling which is typically associated with mono metal bullets.
These bullets do not mushroom, but instead, fracture. After 1-2? of penetration, 3-4 petals will break off and radiate outward from the main wound channel about 2-3? creating massive trauma. They will expand down to 1600fps. The required twist rate for this bullet is 1:17″ or faster.
