Clamp the left to right or top to bottom?

I was thinking of making a tool to compress each barrel like a pex ring tool, but slightly longer. My concerns would be if the barrels could take it, and if I could keep it straight. Not as "good" as threading for choke tube's, but...

Many years ago the cheap pex ring tool people used was closed with bolts instead of compound lever handles.
