If you order Dutch Schoultz's Black Powder Rifle Accuracy System for $15.00, he has information in that package that tells you how to make a perfectly adequate short starter out of parts and pieces you may have lying around in your workroom.

If you will look at any of the suppliers, you can find the needed ferrules for the ends of the rods, as well as commercially made short starters pictured, so you can make your own decision.
I made my own short starter using the fork of a deer antler I had left over from a knife making project. I also had some ends of ramrod shafts that I cut off when I shorted a ramrod for my gun's barrel length. I did not put metal ferrules on the ends of the rods, but did use a drill bit to cut a cup out of each end. I used that short starter for several years without any problems.
The bare wood ends would collect lint, and grease, but that was simply a matter of remembering to clean the short starter at the end of a shoot, along with the rifle.
I won a T/C short starter at a shoot later, and it comes with a wooden ball, metal rods, and the longer rod has a muzzle protector made of brass on it. I have been using it since with my .50 caliber gun.
They are still sold. I don't use in on Woods walks, or survival courses, where points are deducted for anything that "Modern", but I use it for most everything else. I do plan on coning the muzzle on that gun, and when that is done, the short starter will be retired- permanently.
