[QUOTE="Michael Eichele, post: 314023, member: 1007"] Some shooters say 9.2 or 9.3 is best for the 300 grain pills. Others say 10x for the 300 grain pills. My opinion is that 10x is more than adequete for the 300 grain variety. This opinion is based on stability factor calculations and real world results. If you went with the tighter twist such as 9.3 etc...you would have the availability to run solid copper bullets such as the GS bullets or some of the newer prototype bullets noel is tinkering with. If all you want to run is the SMK or Scenars the 10x will do fine. As far as length, that depends largely on you. I am running 28" of barrel and getting 2750 with the 300 SMK with 91.3 grains of H1000. If this rig was not designed as a back country cannon, I would have gone with a 30" barrel. I sacrifice a bit of velocity for better packability into the back country. Most 338 edge users prefer the full 30" tubes and are getting up to 2800-2850 with the 30". Shawn Carlock who is renouned for his experience and development of the 338 edge is a big fan of the 30" 10x. [/QUOTE]
