Were they talking about Greer's testimony in regards to the S & B 300 Blackout cartridges found at the body and the 5 wounds to her body from that ammunition type?

"It is my conclusion that these items had been loaded into and ejected from the same firearm at some point in time, these matching marks included firing pin marks, ejector marks, extractor marks, and chamber marks."

 How did those cartridge's come out of a shotgun?

 Also at the scene were Federal Premium and Winchester Drylok 12 gauge 3-inch shotgun shells.  Is it being contested that maybe those caused her wounds?  If so why is Murdaugh's defense agreeing that the son was killed with the shotgun and the wife was killed with the Blackout rounds?

 Seems like the defense would want the rifle rounds to be dismissed from evidence instead of agreeing with the forensic analysis.

 Oh I see you mean the description of "AR" being used when the gun has not been recovered and the 300 Blackout can be fired from weapons that are not considered "AR" or "AR Style".

 

"Do you really think that people reading this believe you did not know what was being said in the first post ?"

 I don't know what people believe.  I was under the impression you thought only a shotgun was used.  I was wrong.

 "AR" as a generic term is definitely being over used.
