On another forum I read a thread about stabilizing a Berger bullet in a 10" twist 243.

There were lots of posts and they seemed to alternate between:
1) Works great for me
2) I tried and it was terrible

Myself, I put 75 gr Vmax in a 14" twist 6mmBR and shot at 0.2 moa 3 shot group and a 3 shot group of keyholes. I will mark that one down as marginal.
