Yeah, it was a serious question. I thought there might be some kind of formula they used to determine barrel length to get the most efficiency from the powder charge in their cartridge. After much research, it seems they just made the barrels whatever length they thought would sell the best. Of course, for example, a .44-40 fired from a saddle gun would have more velocity than the same ctg. fired from a 4.75" revolver.
How Did They Determine Optimum Barrel Length?
Back in the day when cartridge firearms were loaded with black powder, how did the gun manufacturers determine the proper barrel length for maximum efficiency of their known boolit (calibre and weight) and their known powder charge?
Did they have a formula or was it a "hit and miss" (pun intended) proposition? There were centuries of experience with black powder prior to cartridge ammunition. In my best guess, there must have been some reference material written down somewhere. The Davenport Formula doesn't apply as it's to determine powder charge for a known ball and a known barrel.
If one was going to build a rifle for a new black powder cartridge, how would they determine the optimum barrel length?

I recently did some research via Marlin Firearms: A History of the Guns and the Company That Made Them http://alpl.ent.sirsi.net/client/en...u=Marlin&te=ILS&rt=false|||SUBJECT|||Subject#by William S. Brophy and when the Marlin Model of 1894 was introduced, it was offered in either a 15" or 20" carbine or a 24" rifle but the rifle could be had in lengths up to 32" at an additional cost of $1.00 per inch.
