I’m pretty sure many of the police officers know whether it was a 22LR or a more powerful centerfire rifle round just by the sound.

I have a few 22s (pistols and rifles). I also have a 22 magnum PMR 30. When I’m on the range with it, other shooters lean over to look at what in the heck is making that godawful noise. It’s probably louder than my 1911s or similar. A very large bark.

Do cops go through some special “round recognition” training?

They found the brass, I heard that the first night. They are just not telling us. My bet is .22LR.

I disagree. Most I have seen have to look at the rear of a shell case to know the caliber.
