One. An friend was given a Charles Boswell damascus gun. He asked me about shooting it and I told him all the usual precautions and warned him to use low pressure only, and suggested powders and loads. He modified a MEC to 2 1/2" and prepared to reload shells for it. He said he was going to use Unique, which I strongly opposed. He said the reloading manuals had about a 20% fudge factor, and he wanted to use up the Unique.
The right chamber blew out after about 6-8 rounds. No one was injured, but the escaping gas hit another shooter standing beside the box pulling the targets. He said it felt like someone slapped him in the face.
He claims it was a stuck basewad, to this day.
