Does anyone know the earliest example or record of a rifled cannon? Rifled firearms existed since the 16th, and possible 15th century, but I cannot find a rifled cannon from before the 19th century. Other "modern" artillery features, like breechloading, existed in that time, so it is a little strange that no one seems to have combined any of that with rifling. Maybe pressure was too much of a problem to make it feasible, considering smoothbore cannons struggled with bursting?
. Funny what you remember, or think you do
