Originally the 6mm rem came out with a 1 in 12 twist and there were problems immediately
Winchester brought the 243 out with a 1 in 10 twist and the rest is history. (The 243 was almost
the demise of the 6 mm Rem in factory rifles. the the 6mm Rem fans were forced to go with the
1 in 10 twist to revive the cartrige.
The 243 Winchester does well with the 105 grain bullets in a 1 in 10 twist so I see no reason that
the 1 in 9&1/8 should not shoot them well.
Velocity seems to be the culprit in fast twist barrels and as long as you dont push the bullet
beyond its limits they work ok. sometimes the bullet shape and body length can have an effect
on twist rate by the way they engrave in the rifling. So your rifle may like one 105 and not another
so try several different bullet shapes.
