This bullet was designed for single shot loading in 50BMG rifles. It is a popular choice among 50BMG match shooters. This MTAC line is 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 Cutting Edge's patented SealTite(TM) 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(TM) band also decreases copper fouling which is typically associated with mono metal bullets. Mfg: Cutting Edge Bullets
