i think it would be unthinkable that there weren't any short/ball starters prior to the 20th century. i'd heard before about the military starter mallet, nothing new at least for me.
however, and as i stated in my opening thread post, i'm focused on the 18th century, not the 19th ... any indications of short starters used in pre-colonial times, the settlement period, the F&I War, the Rev war?
my thinking, albeit per my limited historical reading, is that the fowler was the prime tool for the three most important functions of both colonist and native american - sustenance, protection, war. while accuracy is important, speed of loading for protection and war trump exceptional accuracy over "general" accuracy. a short starter would just be a speed bump and hindrance when loading a patched ball. there were, and still are, many different payload choices - i.e., tow held unpatched ball, patched ball, shot and sundry other projectiles, etc - so the speed of load, enhanced by some measure of thumb pressed prb into a coned muzzle, could also be dictated by the choice of both ball diameter and patch thickness. perhaps a tighter prb that could still be rammed down the tube with just the gun's ram rod. who knows any of this for sure? not me.
