Thanks,

1:14 for all 3.

1:12" is best for all three, especially if you want to use the heaviest and/or longest of bullets.

1:16.5" is the CIP twist for the .416 Rigby, CZ uses that. It may do poorly with 400-grain monometal copper or brass bullets, O.K. with 400-grain woodleighs.

1:14" is what Ruger used for their .416 Rigby rifles. Remington and Winchester used the same 1:14" twist on the .416 Remington.

George Hoffman used 1:14", but was recommending 1:12" shortly before he passed.

The last .416 barrel I bought was a 1:12" for a .416 Dakota.

All my 35's are 1:12" twist:
35 Whelen
35 Brown-Whelen
.358 ST Alaskan

1:14 would be O.K.
but being a graduate of Chubby Checker University, and wanting to use any and all bullets out there to best ability, I know that 1:12" TWIST is best.

No slower than 1:14", no faster than 1:12".

use a twist calculator, greenhill formula, and go about 1 twist faster than called for...

Thanks, I orderd the .35 Whelen barrel in 1:12. I have not ordered the .416 yet, but probably 1:12. Still debating myself whether I want a Rigby or Remmington. Nostalgia versus the practical!

I assume you mean 1 "inch" faster twist, i.e., one revolution in a 1" shorter distance; not one additional revolution in the same distance - BIG difference.

Kreiger, Lilja and others have computer programs..just tell them the bullet weight and muzzle velocity...or other pertinent info and they will figure out the optimum twist. I let experts do what they do best and get out of the way.

Duane, do you mean to imply that all the information that we get off the internet isn't from experts?

Shocking!
