A dedicated subsonic-focused pairing for anyone building out 300 Blackout suppressed loads without paying full retail on both halves. Swiss P primed brass — produced on special order under the Norma headstamp — pairs one-to-one with a heavy-for-caliber 220gr pointed bullet suited to subsonic velocities, where weight and stability matter more than speed. The bullet's double cannelure locks in a secure crimp against the heavier powder charge and bullet setback that subsonic loads put on a case. Both components are matched 1:1, giving you everything needed for a full run of subsonic ammunition at a price built to make trying 300 BLK subsonic more approachable.
