AM10_9MM_147gr_JHP.DOCX

SPECIFICATIONS/REQUIREMENTS

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

AM10, AMMUNITION, 9mm 147gr JHP, Match, Minor Power Factor, Custom Loaded

10a. PROJECTILE: The projectile shall be 9mm 147grain JHP. All projectiles must derive from a single OEM lot. Evaluation criteria – inspection, accuracy

10b. CASE: New, unfired 9mm 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.

10c. PRIMER: Factory Specifications primers obtained from a single OEM lot that meet performance requirements. Evaluation criteria – accuracy, velocity and function standards

10d. 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

10e. ASSEMBLED CARTRIDGE: Overall length should not exceed 1.110 inches nor be less than 1.095 inches when measured from the tip of the bullet to the base of the cartridge. Crimp measured at the case mouth shall be 0.376” diameter or smaller. Evaluation criteria– Inspection measurement; Pass / Fail

10f. LIVE FIRE TESTING: All candidate ammunition will be fired through a 4.9 inch, Beretta M9 9mm 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.

10g. ACCURACY STANDARDS: Five groups; ten-rounds per group, fired at a target placed 50 yards from the muzzle. Measurements are to be computed from center to center of the widest shots (extreme spread) in each of these ten round shot groups. Extreme spread of these five groups, compiled and averaged, shall not exceed 1.90 inches and the extreme spread of any individual shot group may not exceed 2.25 inches. Evaluation standard – Pass / Fail.

10h. MUZZLE VELOCITY: With the ammunition conditioned at 70 degrees, plus or minus 5 degrees, and starting with an ambient temperature bore/barrel, the velocity of three consecutive rounds are averaged and shall produce a power factor (PF) of not less than 132 and not more than 135 using the USPSA method of calculating PF (projectile weight X velocity / 1000 = PF). Velocity will be measured using a chronograph with the center of the chronograph array placed 15 feet from the muzzle. Evaluation standard – pass / fail.

10i. 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, Glock G17/G34 and/or Beretta M9/92FS. Evaluation criteria – zero ammunition related malfunctions and zero ammunition defects. Pass/Fail.

10j. 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 individual box in that case, shall be labeled with the lot number, caliber, projectile weight and projectile type.
