AM08 9MM 115gr JHP.pdf

SPECIFICATIONS/REQUIREMENTS

The contractor shall furnish ammunition in accordance with the specifications listed below.

AM08, AMMUNITION, 9mm 115gr JHP, Match, Custom Loaded

8a. PROJECTILE: The projectile shall be 9mm (0.355”), 115grain Hornady XTP. All projectiles for this line item must derive from a single OEM lot. Evaluation criteria – inspection

8b. CASE: New, unfired brass case obtained from a single OEM lot. Overall case length of 0.749” with a tolerance of + or - 0.001”. Evaluation criteria– inspection, measurement; Pass / Fail.

8c. PRIMER: Factory specification primers that meet performance requirements and are from a single OEM lot. Evaluation criteria – accuracy, velocity and function standards.

8d. PROPELLENT: The manufacturer shall establish the powder type and charge weight to meet performance requirements and maintain chamber pressures within SAAMI recommendations. All powder for each lot of ammunition must derive from a single OEM lot. The powder used shall not be overly sensitive to atmospheric conditions so as to severely degrade accuracy, nor cause large variables in velocities or excess chamber pressures, while operating in temperatures ranging from 30F thru 115F. Evaluation criteria – accuracy, velocity and function standards.

8e. ASSEMBLED CARTRIDGE: Assembled cartridge overall length should not exceed 1.080 inches nor be less than 1.075 inches when measured from the tip of the projectile to the base of the cartridge. Crimp measured at the case mouth shall be 0.376” diameter or smaller. Evaluation criteria– Inspection Pass / Fail.

8f. LIVE FIRE TESTING: All candidate ammunition will be fired through a 5 inch, KKM Precision 9mm match barrel mounted separately from the firearm in a fixture to test for accuracy. The ammunition will then be fired through assembled pistol(s) to test the ability of the ammunition to reliably function the firearm.

8g. ACCURACY STANDARDS: Five groups; ten-rounds per group, fired at a target placed 50 yards from the muzzle. Group sizes are to be computed by measuring the distance, center to center, of the widest shots (extreme spread) in each of the ten round shot groups. Extreme spread of the five groups, compiled and averaged, shall not exceed 1.25 inches AND the extreme spread of any individual shot group may not exceed

1.40 inches. Evaluation standard – Pass / Fail.

8h. MUZZLE VELOCITY: The average velocity (corrected) of the ammunition when conditioned at 70 degrees, plus or minus 5 degrees, shall be 1090 Feet Per Second, + or – 15FPS, and contain extreme velocity spreads of less than 30FPS. Velocity shall be measured during accuracy testing using a chronograph with the center of the chronograph array placed 15 feet from the muzzle. Each of these groups will be averaged and then those five results will compiled and averaged. Evaluation standard – pass / fail

8i. FUNCTIONAL CHARACTERISTICS: Candidate ammunition must burn clean and leave minimal residue. Ammunition must function reliably from assembled firearms and there must be zero malfunctions that are attributable to the ammunition and zero ammunition defects. The function reliability test will be conducted with one or more of the following pistols; 1911, Sig M17/M18/P320, Springfield XDM and/or Beretta M9/92FS. Evaluation criteria – zero ammunition related malfunctions and zero ammunition defects. Pass/Fail.

PACKAGING: The cartridges shall be assembled in identifiable lots. Ammunition will be packaged 50 rounds per box, and 20 boxes (1000 rounds) per case. Each case, and each individual box in that case, shall be labeled with, at a minimum: lot number, caliber, projectile weight, and projectile design.
