The problem with Mythbusters is that they often go outside the realms of the myth and make in any effort to make the myth at least "plausible".
I don't know how they'd do it, but I can see them trying to reinforce the receivers, and if they can get at least one bullet going down range, regardless of what happens to the shooter or gun, they'll slap on the "plausible" verdict.
I wouldn't even approach them.
Not to mention that it will circulate this story to those I mentioned earlier, and regardless of what Adam, Jamie, and Co. conclude, they'll run with it.
