The 130 Speer HCFN will work swell in the 308 at reduced speeds. I base that on how many good reports I've read of those who used it in their 30-30s and 30-30 Ackley Improveds. I got great accuracy with it in a M336 30-30 AI myself, but killed no game with it. I've shot a lot of 125BT and loaded them for a friend for his 30-06. Keep your speeds under 3K and it should do very well in the .308.
