Underwood Xtreme Hunter Platinum ammunition in 10mm Auto (brand part no. 942) is a hunting-handgun load built for deep penetration on tough game. Underwood backs this load with the quality control shooters expect from a name they already trust. At the heart of this load is the 150 gr bullet with a solid monolithic design, matched to the 10mm Auto platform shooters already run. In our handgun ammunition lineup, this is the Underwood load built for that job.
