How do I get my muzzle break off?

I'll add the Kimber is lefty loosy. Get an 1/8" punch and put through the holes then a sharp rap with a dead blow hammer or brass hammer if you have it. Soak treatments above will only help not harm too...

I've used the hack saw many times too. Gunsmiths may revolt but I have recrowned many rifles with a basic kit from Brownells. They aren't as pretty but results have been excellent.
