They might not be able to tell directly for the reasons Egirl stated, but they might be able to tell indirectly:
I think the firing pin on each fire arm is unique at the microscopic level. The firing pin is what strike the primer in the shell or bullet casing. This ignites the primer and also leaves a mark.
If the shot gun was pump action (most are, but some users prefer olde style breech loading shotguns), the user ejects the shell after being fired, then "racks" a new shell into the chamber to be fired again.
So, if the ejected shell(s) can be found and the firing pin marks are unique, the investigators can say that a certain shot gun was, in all probability, fired in a certain area.
It could also be argued that a previously fired shell was ejected in the area, but not fired. This argument, however, may not carry alot of weight with a jury- espescialy if two ejected shell are found.
Don they know it was a pump shotgun that was used? I wondered if it was a double barrel that possibly gave the witness time to act when the shooter would have had to reload.
