Method Black powder replica guns?

Will it do the work? I think my grandfather has one

The blast of the gunpowder should do it, but it would be best to ask your grandfather a few questions about it and maybe try it out, before attempting. There's a lot that can go wrong, like too much gunpowder or too little, both ending in a failed attempt.

Of course it will work. To be sure, you need to use a barrel at least 5 inches long.
