CSI goof: There is no Ruger 10/22 .223 caliber

We are watching CSI Miami and Frank is having a hard time … he wants me to know that there is no Ruger 10/22 .223 caliber gun.  This isn’t the first time they’ve talked about a gun that Frank says doesn’t exist. 

He even went and got a shell that goes into his Ruger 10/22 and a .223 shell and showed me how they are very different sizes.  One is twice as big as the other.
