I use mainly 68 and 70 grain bullets what would the best twist rate be for this ?? may lasy barrel was 1 in 13 my new barrel should hacve been a 1 in 12 but the smith that ordered it has totally messed it up and even sent the wrong contour as well as a 1 in 10 twist,anyway Iam now informed that the company whos barrel iam having only does a 8 9 or 10 twist,will I be OK with a 10 twist
 
Ackley,
My 243 Rem had a 1-9 1/4 twist and shot 68grn Bergers and 70 SMKs extremely well so i think a 1-10 will be okay.
However you should always go for the minimum twist that will stabilize your chosen bullet and Bergers recommendation
is worth taking note of.
