A friend just asked me if there was any way to get his Greener Mk III Police shotgun shooting again.
These guns use a proprietary 12/14 ga. shotshell which I'm assuming is no longer available.
Are there any relatively inexpensive conversion options available? I can post pictures but the relevant information on the gun is 12 in a diamond 2 7/8" x 186. A standard 12 ga shell will slide in for about 1 1/4".
