[QUOTE="Michael Eichele, post: 466931, member: 1007"] I maybe off base here but I am not sure how much more bullet weight the 308 can handle than the 208. You cannot get enough powder in a 308 to make anything heavier than a 208 have any significant velocity. At least not enough to make the higher BC worth while. If the 308/208 AMAX isnt enough for you then you should most likely be looking to another cartridge. The 308/208 combo is nothing to sneeze at as it is. My idea of a perfect 308 winnie bullet is 175-190 grains with a .6 to .625 BC that will expand on game as low as 1400 FPS and hold together on a shoulder shot at 2800 FPS. A 190 with a .625 BC would be about the best overall balanced bullet between speed and BC. Typically from a 26" barrel a 190 can be driven any where from 2600-2750+ with the right powder. Even at that, the 190 with a .625 BC would only have a very small benefit in wind and energy over the 208. The real difference here would be a combo near that of the 308/208 with a bit less recoil and a bullet that will hold together a bit better at close range. Kind of sounds like the 177 GS bullet except I cannot bring myself to believe that the published BC is any where near reality and I would need a new barrel to stabilize it. I would gladly get a new barrel if I thought the BC was close. M [/QUOTE]
