I have been asked and read alot lately about which is a better cal. 54 or 58? So I decided to look at some reference material (beartooth bullet ballistic site and the Sam Fadala new 2nd edition blackpowder manuel) and this is what I came up with. I am no way bias as to the outcome because I am looking at a 20g/62 cal smoothbore :grin: Hope this helps.
