Does anyone have or can generate the decel rate for PGU-28 ammunition fired from a M61A1 cannon?
I have this as far as performance:
PGU-28 Starting with Block 50 (as far as the F-16 is concerned anyway), provisions have been made to fire the new 'hotter, faster, farther' PGU-28 round. It reputedly travels three times as far as the standard M53 round, effectively closing the gap between the Sidewinder minimum engagement range and the gun's maximum engagement range.
Its rate of fire depends upon two selectable firing modes: 4,000 (GUN LOW) and 6,000(GUN HIGH) rounds per minute (maximum rate is 7,200 rounds per minute). Muzzle velocity is 3,450 ft (1,052 m) per second, with an effective range from half a mile out to
19,700 ft (6,002 m). The system lifetime is about 150,000 roundswith a 15,000-round mean failure rate. Average recoil force is 2,661 lbs (1,207 kg) at 4,000 rounds per minute and 3,818 lbs (1,732 kg) at 6,000 rounds per minute.

A 9mm MAY expand, but a 45 will NEVER shrink!

Don't know about the variable rate, someone who actually worked the plane can clarify that.

Some interesting stuff there. If you can find out how much the shell weighs, then you can calculate the decel.

Ignorance may be bliss, but it sure ain't fun!
