Narrowing the throat of a large casing?

Question to you ordnance guys? I have a 57mm and a 75mm casing I want to receive their appropriate AP projectiles. The throats of the casings are a bit too large, so I want to narrow the opening without deforming the circumference.  I've tried a hose clamp around a PVC collar but can't get enough pressure because the screw strips its band before narrowing the throat of the casing.

 

Any suggestions?

Anneal the brass to soften it. I'm sure You tube has a video on how to anneal.
