The 7mm would be a .257 cal.
When did that happen???? Where i come from a 7mm is a .284" diameter bullet, and it's considered 28 cal..
The .257 is considered 25 cal..

You are right DM, I don't know where I got that from. I think they developed the 7mm Mag from the .257 caliber or something like that.
Anyhow, you are right, it is a .284 [
