Question re: 9.3 320 grain Woodleighs

Guys, my CZ 550 9.3X62 has a 1:9 inch twist. I am not sure but I think my Blaser does as well. Is that fast enough to stabilize the 320 grain Woodleighs?

Although CZ USA states their 9.3X62's have a 9"twist, myself and others have measured the twist and discovered our rifles had a 14" twist. That said, I beleive even a 14" twist is fast enough to stabilize 320gr. bullets. Measure your barrels twist yourself to be sure.
