Winchester Silvertip Defense 300 Blackout ammo pairs a 150-grain Winchester Defense Tip polymer hollow point with supersonic velocities — 1900 fps at the muzzle, delivering 1202 ft-lbs of energy. Designed specifically for personal defense, this Winchester load balances penetration and controlled expansion across common barriers, making it a reliable choice for home defense carbines chambered in 300 AAC Blackout.
Performance at a Glance
The Winchester Defense Tip features a polymer insert that initiates expansion on impact while the jacketed hollow point design ensures reliable feeding from AR-platform magazines. At 1900 fps, this load remains supersonic out to typical engagement distances, maintaining trajectory consistency and terminal performance. The 0.392 G1 ballistic coefficient provides predictable drop and wind drift for close-to-mid-range work.
