Cutting Edge MTAC rifle bullets in .338 caliber deliver match-grade precision for serious long-range shooters and reloaders. These 277 grain solid copper projectiles are engineered for consistency across target shooting at all distances, combining a high ballistic coefficient with Cutting Edge's proprietary design to eliminate the fliers and copper fouling that plague many monolithic rounds. If you're loading ammunition for precision rifle work and want bullets that shoot like they're supposed to, the MTAC line is built for repeatability and clean barrels.

Each bullet is machined from solid copper bar stock on a CNC Swiss lathe, not stamped or cast. That precision manufacturing translates to tighter dimensional tolerances and more consistent flight. The standout feature is the SealTite band—a patented band diameter slightly larger than caliber that seals the bore during firing. It reduces gas blow-by, which is the hidden cause of vertical stringing, and it also cuts copper fouling, a real benefit when you're logging rounds downrange without wanting to scrub your barrel every few shots.

Before you load a round, check your rifle's twist rate: these bullets require 1:9.5" twist or faster. If you're shooting subsonic loads that transition through the transonic range, bump up your twist rate requirement by one inch (e.g., 1:9" instead of 1:10"). That's the tuning secret for reliable performance in that velocity window. Each box contains 50 bullets, ready to load.
