Is doesn't seem too outlandish that a .223 could have been sabotted into a .30.

Anyone know if a sabot requires any different seating or crimping in the case that might give it away?

But what would be the advantage of that (aside from the higher velocity possible)?

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.
