Homemade rifling tool for barrels

[Clinton]

Love the Idea and concept I was thinking a rifle button attached to some allthread in the same frame powered by a drill or hand crank ??? just thinking out loud

Funny you should mention that. Check my latest post. And apologies for not responding. I don't get on here much and don't seem to get emails when there's a post.

And here's a finished barrel that's been polished with lapping compound. In fact the grooves are packed with it in this photo. That has been scrubbed out.

I am curous, is there a standard rate of twist or? If someone was to have it twist more per inch, would the projectile spin faster and be more accurate? Asking out of ignorance. Beautiful work!

Twist is a complicated relation between bullet weight, barrel length, caliper, distance to be accurate, you can have a .455 muzzle-loading rifle with a long twist which is more accurate than a rapid twist hunting .30 modern rifle, it's just a problem of what you want as result. ;-)

Here is some information on rate of twist.
