Finally got a solid foundation of tools and my finances under control to the point where I feel comfortable embarking on my first "Real" gun build. I've decided to start with a relatively simple small caliber inline muzzleloading pistol for target and small game use because the materials would require minimal investment and I wouldn't need to source and labor. I was set on a .32 caliber with patched round balls as the projectile. Little did I know how difficult and expensive it would be to find a .32 caliber barrel with a twist rate slow enough. The barrel is the one component I don't have the means to nor am I comfortable making from scratch and the only .32 caliber blanks and liners I can find are for centerfires with twist rates far too fast for use with PRBs or even sabots.
So theres a few ways I can salvage this idea. One is to acquire a traditions crockett .32 pistol barrel and convert it to inline, a process I'm not sure how I would go about, whether it would be worth the effort, and don't really have any desire to perform. The second is to source a barrel from a percussion revolver in .31 or .36 which seems like the most likely resolution at this point. the third is to use a .32 SP or .32-40 liner with a twist rate of 1-14 and 1-16 respectively. Would either of these twist rates for patched round balls produce acceptable accuracy out of a 10 inch or so barrel?
