Ammo Inc. Signature Features The Ammo Inc. Signature is loaded with a 55-grain full metal jacket projectile selected from proven projectile designs and tuned for the specific terminal performance requirements of the .223 Remington chambering delivering extreme accuracy and consistency from round to round. At 3 201 fps and 1 251 ft-lbs of muzzle energy the Signature delivers a flat consistent trajectory suited to target shooting at extended rifle ranges without the velocity drop or energy loss that slower loads produce at distance. Brass casings provide reliable chambering and extraction across all action types and are fully reloadable for shooters who want to extend the value of their bulk purchase even further. For target shooters and range enthusiasts who want a precisely tuned accurate .223 Remington load backed by Ammo Inc. s commitment to extreme accuracy and caliber-specific performance the Signature delivers consistent results that less carefully developed loads cannot match. The 200-round bulk box gives shooters a substantial supply for extended target sessions without the need for constant resupply and the brass case construction ensures consistent dimensional integrity for reliable function across a wide range of .223 Remington rifles and carbines. Ammo Inc. s Signature line is built on the principle that each caliber deserves a projectile and load developed specifically for its performance envelope rather than a generic solution applied across multiple chamberings.
