View Full Version : CZ 550 actioned .416 Rigby: best barrel twist?
January 18, 2000, 05:43 PM
I have decided to build a Rigby on the 550 action, and need to get a better barrel than the one provided with the action. Any recommendations for twist rate?
The barrel will run 22-24 inches, medium taper. It will not be ported.

Mad Dog, the recommended twist rate for the .416 is 1-14" for all bullets. If you want to check that and you know the length of the bullet you plan to use go to http://www.digiweb.com/dputzolu/VIIIB6.html and work Greenhill's formula. George
