Went with a 1-9" twist with my 6x47 Rem. The 95 grain Nosler Ballistic Tip shoots great, just as accurate as any of the lighter weights.
Never planned on going with anything heavier than 90-95 grains.
Speed kills. and I don't have any long range shots that would benefit me by going with a higher BC bullet such as the 105 gr. A-max. The balance of good velocity with a decent ballistic coefficient is more important to me in the smaller cartridges.
