I believe Thompson Center recommended a .550" round ball for the .56 caliber smoothbore Renegade. I don't have any of Larry Callahan's moulds, but he has a sterling reputation and I believe he can cut a bag mould for a round ball in just about any diameter.

I do have a .550" roundball mould from Moose Moulds. It was not cheap, around $100.00 if I remember correctly, but it is very nicely made and you can't beat their service.

Track of the Wolf carries .550" cast roundballs, if you want to test them before you go to the expense of getting a mould. I have found I prefer more than .010" clearance or "windage" in my smoothbores, if the ball is patched, so you might like a smaller ball in the .56 Renegade.

On a historical note, you see occasional references to a "half ounce trade ball" in the literature (see Gooding's Trade Guns of the Hudson's Bay Company, Hamilton's Colonial Frontier Guns, and the Earl of Southesk's Saskatchewan and the Rocky Mountains). A true half ounce ball would run 32 to the pound, and would measure .526". However, from the reading I have been doing (see references above), it appears that the basic "trade ball" was actually .550", which is a true 28 gauge (28 balls to the pound). The writers of the period evidently "rounded off" a little in their estimation of ball weight or size. Typical smoothbore trade guns of the late 18th and 19th centuries (e.g. Northwest guns) usually had bore diameters of about .570" - .600", or in the neighborhood of 24 gauge. It would appear the Indians shot markedly undersized balls.

In any event, I hope you find what you need to get that Renegade shooting again. A 28 gauge shotgun brush will be a perfect fit for cleaning the bore, and if a .54 caliber jag does not give a tight enough fit, just use a thicker patch, or double up with thin patches. The difficulties you hear about keeping these guns shooting and maintained because of the unusual bore are greatly exaggerated.

Best regards,

Crooked River Bob
