Reviving an old thread.
I've worked up some tack-driving loads for my son's 308 Win using 180 gr Speer Grand Slams, as in 1-hole 5-shot groups at 100 yards. No complaints at all on their utility for white tails and anything else in that class, but at only 2550 fps, they run out of steam by about 250 yards or so and was thinking about working on a different load that might give him another 150 yards.
No specific hunt in mind, but he does live on the other side of the country from me and could have opportunities anywhere.
My thought is either Scirocco II 165 gr or Accubond 165 gr. I should be able to get both of those to 2700 fps, both with BC at .47.
