[QUOTE="mcdil, post: 2259509, member: 112571"] I'll have to qualify the 308 Win in that it will need a 1:10" twist. Many newer factory rifles are coming in that way already. The majority are 1:12", however. If I can assume a 1:10" twist and a 22" barrel, the 308 Win should have no trouble crossing 2900 fps with the 153 gr. To guarantee perfect terminal performance, that allows a 1:10" twist 308 Win to be an 800 yard gun at sea level, and further at elevation. We will address the 1:12" twist very soon, potentially the 6th bullet released. It will be an excellent option for the majority of 308s. It will shake out in the mid 130s to give you perspective.
