Oh I wasn't supporting the idea of a modern .79 pistol that uses rifle rounds (although theoretically I guess a .79 pistol round could be developed, it would just have the ballistics of a brick past a few dozen yards and only do roughly what a shotgun slug does), I was just pointing out that flintlocks did exist in those calibers. Though, those pistols were best used as clubs the accuracy was so horrible. The smaller caliber pistols were generally far far more accurate.
