Our MTAC line is precision-machined from lead-free solid copper bar stock using a CNC Swiss lathe, resulting in high ballistic coefficient (BC) solid bullets designed specifically for target use at all ranges. A key feature of these bullets is our patented SealTite band, which is slightly larger than the caliber diameter and wraps around the bullet. This design helps eliminate fliers by preventing gas blow-by, ensuring more consistent accuracy. Additionally, the SealTite band reduces copper fouling, a common issue with mono-metal bullets, ensuring cleaner barrels and more reliable performance during extended shooting sessions.
