Damit, I had a conversation with a guy back in May who had a MA cannonier license. He said it was very difficult to get but gave some pointers. Wish I could remember.
My late uncle had one. I had the impression the process was straightforward, but it was at least 15 years back, maybe longer.
Don't put in too much powder, don't use too tight wadding and don't look down the bore when it's loaded. Shout fire in the hole and high tail it to a safe distance. Outside of Mass, that's basically all you need to know.
