I am abit at a loss of what twist rate to choose for my 9.3 x 64 brenneke. My Viht. manual is showing use of a 14 twist and my Nosler is also showing a 14 twist. Is not this a bit too fast? Suggested advisement here on shooting heavy bullets is to have a 10 twist rate. The 9.3 x 62 is shown with a 10 twist in my manuals.

I am gonna go with a 25.5in. bbl Douglas and a 1909 ARG. action, Sunnyhill metal, Timney trig, Wisners 2 pos safety. Contacted Stuart Sat. to do the metal work.

Pointers?

thanks

I just checked my New old Husqvarna 9.3x57 with a 24 1/4" barrel and its 1-14".

9.3x62 CZ550 12 twist (rebore by Dan Pedersen per my specification)...just in case I wanted to step to the 320 grainers.

Just a note a 14 twist is slower than a 10 twist. 14 equals one complete rotation for every 14 inches of forward movement while the 10 is spinning one in 10.

My 93x62 has a 12 twist and stabilizes 286gr bullets quite well.

A 12 twist settles it. thanks.
