It takes a 200gr FTX .000867 seconds to exit a 16" 1:24 barrel at 2412fps (realistic accomplishment).
As it exits the muzzle It has rotated .66 revolutions.
Calculate Rev/sec
1/.000867 = 1153 X .66 = 761.24
Convert Rev/sec to Rev/min
761.24 x 60 (seconds in a minute) = 45,764 RPM
That's a lot of stability!
