I have seen listed twists on barrels from 1 in 12" to 1 in 16" and everything in between.

Is there a best twist?

Do you take into accout bullet wieght like the lighter calibers?

Any feedback would be welcomed.

14 for all weights.

Bullet length, not weight, is the primary factor for calculating proper twist rate. Granted, a longer bullet in a given caliber will also normally be a heavier bullet, but that is not always the case.

Original 416 Rigby rate was about 1:16. I ordered that for the one I am having built.

I put a 1in12 in mine in a douglas barrel Iam very please she well put all the bullet of differant weights into one hole. A large hole but then 5 .416 make a big hole anyway.

I always chose the fastest twist for the caliber Iam shooting.

A-Square's "standardization" of the .416 Taylor was with a 10" twist.

.416 Rem is 14",.416 Hoffman is 10", .416 Rigby is 16.5" and the .416 Weatherby is 14" (all from the same source).

A-Square liked the faster twist to stabilize solids in bone.

Jim,

Did anyone at A-Square ever explain that theory to you, because I would love to hear it.
