Underwood Ammo 10mm Auto 140 Grain Xtreme Penetrator Solid Monolithic Nickel Plated Brass Cased Pistol Ammo, 20 Rounds, 648

I've been fishing in Alaska since 1984. These Underwood loads with the Lehigh Defense Xtreme Penetrator bullets perform like no other load on the market that I've seen. Check out the numerous YouTube videos and I think you'll quickly agree. I've never had a confrontation with a bear in all my time up there, but we see them on a daily basis. These are serious loads for dangerous encounters.
