I am a fan of the heavy blood trail also, the only bullet that I did not get a good blood trail from was a 140 Sierra BTSP from my 260. Hard quartering shot @ 20yds, hit the offside shoulder with no exit. No more Sierras for me.
The deer I have shot with ballistic tips from my 30/06 have been down quick with heavy blood trails, I shoot 180s from it and I have never recovered one from a deer as all have passed through.
Look at the Barnes Vor-Tex ammo if you don't reload. They show a 150 TTSX for the 308 Win. I am much a fan of the 130's, again from my 30/06's.
