When this word was first introduced to me it referenced the bullet expansion to the bore for sabot-less shooting. When the onrush pressure impacted on the bullet this is when obturation occurred. Now the amount of obturation is also dependent on the bullet’s malleability (ease of workability). This also got me to wondering does this play a role with sabot/bullets? Okay time to do a little research on the definition of obturation.
What is obturation in firearms? With reference to firearms and air guns, obturation is the result of a bullet or pellet expanding or upsetting to fit the bore, or, in the case of a firearm, of a brass case expanding to seal against the chamber at the moment of firing.

I find it interesting how making a small change to a load can affect how a bullet will obturate. A gentleman on another site shot some .50 cal bullets recently out of his TC Omega using a BH209 load. He used a veggie wad under the bullet and got keyholes, he then used a sabot with the petals cut off as a sub-base and got nice round holes in the target.
