"They could match extractor marks on the shell, yes."
If they don't have the gun and it's registered: Highly unlikely, unless it being registered they also get a spent shell casing with the extractor marks and firing pin indent on the firing cap. Also, if you don't "police" your brass, they have the shell casings at the scene, where there is likely a casing with your finger prints (loading the firearm) and possibly DNA (sweat or blood on the casing).
Realistically though, if it's a standard shotgun, smooth bore barrel, and you shoot rifled slugs or buckshot and leave no evidence of the shell casings behind, they would have a hard time matching it to just the projectile part of it.
