Somewhere in the not too distant past, I saw a very comprehensive web page with the standard rate of twist for rifle and pistol calibers. I'm sure I'm not the only one who's seen it. Does anybody have a link?

An older version is in the Lyman Reloading or Cast Bullet Handbook.

If you can't find it elsewhere, send a PM & I'll scan it for you.
