[QUOTE="MontanaRifleman, post: 294302, member: 11717"] azgutpile, In the long range game, BC is the biggest factor in getting bullets down range. The higher BC bullets will be heavier, and more importantly as far as twist is concerned, longer. These bullets require tighter twists than the shorter, medium weight bullets of the same cal. The 210 Berger VLD advertises a twist of 11". However, the 210 JLK VLD, which is almost identical to the Berger, advertises a 10" twist. You could probably get away with the 11 twist. But, IMHO, it's better to be on the conservative side. The velocities of the RUM will be friendlier to the lesser twists. That being said, Berger is developing a a heavier/longer, higher BC bullet that will almost certainly require a 10" twist, if not a 9". The 240 Sierra MK, almost certainly requires a 10" twist if not a 9". There are a few custom/wildcat bullets that require 8"-10" twists. I will likely be trying a GS HV 177 (monmetal) in my 300 RUM, which requires a minimum of a 10" twist and would likely be better with a 9" twist. There is also another monometal being devloped which will require a minmum of a 9" twist. If you have no plans of shooting anything with a higher BC than the 210 Berger, then the 11 twist will do well for you. But if you want to try any of the higher BC bullets, you'll need a tighter twist. Hope this helps, -MR [/QUOTE]
