Saboting would leave absolutely no markings on the bullet as it is simply a plastic jacket that goes around a smaller bullet.

The problem with saboting is that the rifling in a barrel is typically selected for a bullet of a specific weight to acheive maximum stability and accuracy. A .223 is typically rifled with one complete twist every 9 inches, called 1 X 9, while a .30 caliber barrel is typically rifled with a 1 X 12 twist rate.

A saboted bullet suffers in the accuracy department to such a degree that a head shot at 100 yards is about half as likely to be successful.

Will rifling be left on the discarded sabot parts? A shooter will not be able to recover his sabot parts; the police certainly will.

Doesn't the velocity figure into that too? If the velocity were 1/3 faster with the sabot round, the bullet spin rate, in terms of revolutions per second, rather than revolutions per foot of forward motion, be the the same as the slower round fired from the 1 in 9 twist barrel.
