Well I bought a birdshead Vaquero about a year ago, which has been setting in my safe. I was cleaning up today and came across the box with the spent shell from Ruger firing the gun. So I though why not give it a look, well you can imagine my surprise to find out it was 45 ACP. I have a number of Vaqueros and they are all 45LC and I thought that is what I bought. Wrong 45ACP. I have never owned a 45ACP revolver but an guessing it need half moon clips. Should they have come with the gun? If not is Ruger the only supplier?
