[QUOTE="HarryN, post: 1015792, member: 69773"] The 308 has a tendency to be less stable than people think, especially at point of entry in a standard twist barrel. The reason is that it was designed that way so that a solid military bullet would tumble to cause damage since expanding bullets are not allowed. From what I can tell, a good way to visualize copper bullet use is to imagine them as "one caliber smaller", so your 308 will behave more like a 7mm-308 or 243. Using GS Custom's offering and charts as an indication, a suggestion would be the 308130HV080. Yes, 130 grain. The listed standard twist for a 308 is only 1 twist in 12, so unless you use a non expanding solid, 150 grains seems very optimistic, which is typical of Barnes marketing strategy. I don't have any skin in the game, but I will admit to being a bit pro- GS Custom and less so thrilled with Barnes. Not entirely sure why, but it is true.
