Underwood 458 Socom Ammo 300 Grain Nosler Ballistic Tip Polymer Tip Box of 20<\/h1>\n

Product Overview<\/h2>\n
\n
\n
\n

Nosler Ballistic Tip Hunting bullets have been trusted by hunters for nearly 25 years. They are precision made and individually inspected for the utmost quality which translates to incredible accuracy with every shot. The heavy jacket base prevents bullet deformation during firing and holds together at extreme velocities as well as a poly-carbonate tip that resists deformation in the magazine and initiates expansion upon impact. The bullet’s mid-section keeps it together at any velocity until impact, and a uniform, pure lead core eliminates possible imbalance and erratic flight caused by air pockets<\/p>\n

As with all of Underwood Ammo rounds, they utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.<\/p>\n
