20rds - 10mm Underwood 200gr. Nosler JHP Ammo Details
Underwood ammunition is manufactured in Illinois and specifically intended to meet the needs of hunters, competitive shooters, and citizens that keep firearms for self-defense. The Underwood company has a great reputation for innovation thanks to their casting methods and quality component selection. These 10mm Auto rounds were made for defensive carry as well as for backup guns that are coveted in bear country. Each cartridge is built using a reloadable brass casing that is nickel-plated for a few benefits: the nickel prevents sweat, humidity, and moisture from corroding the brass and also lowers friction so that cycling is made to be more reliable.Each casing is fitted with a non-caustic Boxer primer for dependable ignition that won't damage your pistol over time. The round is topped off with a 200-grain JHP (jacketed hollow point) from Nosler which matches common heavyweight loads for surefire function in common handguns like Bren Tens and Glock 20s. Nosler's JHP design has a deep cavity and copper jacket which rounds off the border of the cavity mouth in order to make smooth contact with a feed ramp with no hiccups. Upon contact with a target, the projectile will experience wide expansion while transferring devastating energy to the vital organs. That makes this round an excellent choice for handgun hunting or personal protection.

Definitely more in line with the original Norma loads! Worked fine through my Delta Elite and will be my carry load. Very accurate and hard hitting.

These are my chosen carry loads for my S&W 2.0 10mm. I feel confident in their ability to stop any threat, two legged or four.
