The Cutting Edge MTAC line of bullets are machined out of lead free solid copper bar stock on a CNC swiss lathe. These are a high BC, solid bullet designed exclusively for target use at all ranges. A unique feature of this bullet is their 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. The required twist rate for this bullet is 1:13" or faster. Due to their length, these MTAC bullets are designed to be single fed.
