That's what I was thinking, too, although I have (rarely) seen images of larger pistols with slings. Some of the Boller pistols carried by Dixie Gun Works are examples. I don't necessarily think that is the case with the pistol shown by 1sogdusm, but it may be a possibility.An interesting pistol. The band is from a musket, you can see the remnants of the sling swivel screw slot in the bottom.
Eric, about 20 years ago I built a horse pistol out of spare parts I had around the shop and used a rifle barrel in .54 caliber. The twist was 1-60 and it shoots round balls quite well out to the 50 yards I've tried it. Round balls really don't need much rotation to shoot well I found with this gun. It is quite accurate with a 50 grain charge of 2 F. My barrel is only 9 inches long and I have not run it through my chronograph so don't have any velocity figures for you.I am a flintlock rifle guy and don't own any BP pistols, I made most of my BP guns so I have the process down. My nephew is a gun nut, any kind of gun and has lot of them, he has a lot of big bore unmentionable hand guns and wants us to build him a Tennessee Bear pistol to hunt deer with.
He wants a 14" barrel in .50 or .54.
Do you guys know of any plans for such a pistol? I told him he would have to have the barrel made as 12" is as long as I have seen . I also noticed that 1 in 20 is common for pistol barrels, if this requirement is the best option for a pistol a barrel cut off of a different twist might not work well.
As you can tell, I am in the dark about getting the correct barrel to do what he wants from his future pistol, I am sure he will want percussion.
I was watching a Ky Afield segment where the host was deer hunting with just such a pistol, looked like fun and he did get a deer.
