There is another alternative. If you do a chamber cast, you can have an insert made. Just make sure you choose an low pressure round. He almost never responds to email anymore. Call him on a Sunday morning and he will answer the phone. Remember he is in Alaska.

If you have never done a chamber cast, here are the instructions, scroll down a bit. If a casting becomes "stuck" you can simply pour hot water into the barrel and the cerrosafe will melt out.
