Bullet grain v. Barrel twist

[RASteele]

I just sent Hornady an email asking them to give me the lengths of their .308 IB bullets, so I probably won't hear anything from them until Tuesday.

The twist, however, is 1 in 9.5".

I was just wanting to get a little extra "humph" from my hunting ammo and I'd heard from someone that, unfortunately, "size does matter". At least when it comes to bullets...
