Don't forget the angle of the dangle this shot was taken at. Your 2.1 inches will look shorter from the angle that the 7D was placed at for the shot.

I think you did the math pretty well......assuming the correct bullet velocity (which can vary alot depending on the particular ammo)
1350 ft/secX0.000125 sec= 0.16875 ft
0.16875ft X 12 in/ft = 2.025 inches
It will certainly look like a streak butyou might have been lucky and got the timing right....in the second shot you can see the slide on the gun has started backwards and there are exhaust gasses visible so the bullet has definitely left the barrel....so maybe it is the bullet but.....
Also the shutter lag has to be considered which is in the range of 0.05 to 0.080 sec. So... to get it right without a trigger and mulit-flash set up is a bit lucky. The bullet could move60 to100 feet between the time you push the button and the picture is taken!
If you try again, attempt to get the sun angle on the bullet and look for a featureless background so it might stand out better.
