c mileski,
Welcome to the board.
Is the barrel you are attempting to make a piece of round bar with a hole in it?  Please look at the thread posted below.  That also was a piece of stainless round bar with a hole in it.
Nobody died.  Be careful my friend.  You may not be the only person to ever fire it.
