MIL-C-46577D
3.3 Manufacturing Process. - All parts and assemblies shall be manufactured
by a process approved by the contracting officer, and no deviation from
that process shall be made without his prior approval. (see 6.3)
3.4 Projectile Extraction.-The force necessary to extract the projectile
from the cartridge case shall be as specified on Dwg. D7258802.
3.5 Electrical Resistance. Primed Case. -The electrical resistance of the
primed case shall be not less than 500 ohms or more than 1,200,000 ohms.
3.6 Projectile Torque. -The projectile shall withstand a minimum torque
as specified by Dwg. D7258802.
3.7 Velocity. -The average velocity of the sample cartridges conditioned
at 68 degrees Fahrenheit (°F) to 72°F shall be 3380 ± 50 feet per second
(fps) at 78 feet from the test weapon muzzle and the sample standard
deviation shall not exceed 40 fps.
3.8 Pressure.-The average chamber pressure
of the sample cartridges,
conditioned at 68°F to 72°F, plus 0.84 times the average range
of the
chamber pressure shall not exceed 60,500 pounds per square inch (psi).
3.9 Waterproofness. -The average velocity (wet) of projectiles of the
sample cartridges conditioned at 68°F to 72°F shall not vary from the
average velocity (dry) by more than 100 fps.
3.10 Accuracy. -The average mean radius of all targets of the sample car-
tridge projectiles at ambient temperature shall not exceed 15 Inches at
a range of 600 yards.
3.11 Action Time. -The action time of the cartridge shall not exceed 4.O
milliseconds at either ambient or - 65°F temperature.
3.12 Incendiary Performance.-The projectile shall function with accept-
able incendiary characteristics upon target impact.
3.13 Drop Sensitivity. -The projectile shall not function on impact upon
a steel plate at a velocity of 52 ± 5 fps.
3.14 Function and Casualty. -The cartridge, at ambient temperature, shall
function without casualty.
3.15 Workmanship .-The requirements for workmanship are as specified on
the applicable drawings, referenced specifications, and the following:
