This Underwood Xtreme Hunter Platinum Edition 10mm Auto 150gr load is sold as a 20-round box (Underwood part no. 942). Underwood calls the Xtreme Hunter the optimum hunting round, and this Platinum Edition loads a 150-grain solid copper bullet in 10mm Auto at a rated 1425 fps and 676 ft-lbs. Its geometry carries the wound cavity deeper into the target than the Xtreme Defender and makes it larger than the Xtreme Penetrator, according to Underwood. The Platinum coating adds corrosion resistance and smoother feeding, which helps in wet or humid conditions.
