I'll also chime in a bit late to the party.
Since this is a hunting forum, I will speak in area of terminal performance. Bullets that are running with higher stability will perform better on impact. The higher rotational vel will keep the bullet point on longer after impact aiding in proper bullet deformation. If a bullet is running with yaw it will cause the bullet to possibly not expand or tumble on impact. I think many of the stories that we hear about bullets not expanding properly can be attributed to not having enough stability to properly expand, not necessarily a bullet failure. In all of our bullet impact testing we found that bullets that are marginal in stability will not perform as well as highly stabilized bullets at low vel.
Most of todays well built bullets can handle the higher twist rates. Go back 10 years ago and it was much more common for jacketed bullets to come apart with faster twist barrels.
So for all the reasons that were given, earlier in the thread, recommending the higher twist rate, and for the aid it offers in terminal performance, I also recommend the 8" twist in the 300wm.
