3. REQUIREMENTS
3.1 General.- The cartridge shall comply with the requirements specified
on Drawing DX10542445, referenced specifications and the folowing:
3.2 Bullet extraction.- The force required to extract the bullet from
the cartridge case shall be not less than 200 pounds.
3.3 Bullet sensitivity.The bullet shall not detonate when the nose
of the cartridge is caused to impact against a stationary steel plate with a
velocity at the point of impact of 55-5 feet per second (ft/sec).
3.4 Residual stress.- The cartridge case shall not split when subjected
to a 1.0% mercurous nitrate solution for 15 minutes.
3.5 Waterproof.- The cartridge shall not release more than one bubble
of air when subjected to a pressure differential of 7 pounds per square
inch (psi) for 30 seconds.
3.6 Accuracy.- The average of the mean radii of all targets of the sample
cartridges fired at 600 yards shall not exceed 5 inches.
3.7 Trace.- When viewed from a line parallel to the plane of the trajec-
tory at each point of observation, the bullet of the cartridge shall exhibit
a visible trace from a point not greater than 100 yards from the muzzle of
the weapon to a point not less than 1500 yards from the muzzle.
3.8 Impact sensitivity.- The bullet of the cartridge, when fired, shall
produce a flash and puff of smoke upon impact against a steel plate placed
at 175 yards from the muzzle and set at an angle of eleven degrees (11) with
respect to the horizontal
3.9 Velocity.- The average velocity of the sample cartridges, condi-
tioned at 70 2 Fahrenheit (F), shall be 1745 ft/sec plus or minus 20 ft/sec
at 78 feet from the muzzle. The standard deviation of the velocities shall not
exceed 14 ft/sec.
3.10 Chamber pressure.- The average pressure of the sample cartridges,
conditioned at 70 2F, shall not exceed 38,000 psi.
