Best 1000 meter bullet for 10 twist 308 Win

For real Lapua data, go to heir site and get Dopplar Radar data, the best ballistic data available for civilians at no charge.

I think if I had to make the choice it would be fast with a decent bc over slow with a slightly higher bc.

For a given caliber, I will always go with the heavier bullet going slower (same bullet profile). They may drop more, but they drift less in the wind, and wind has a lot more uncertainty than distance.

JBM will tell you the same...

Particularly this paragraph:

Assuming constant form factors (drag profiles) heavy bullets will have higher BC‟s than lighter bullets of the same caliber. Heavier bullets will also have lower muzzle velocities than lighter bullets, but when loaded to the same pressure, the higher BC of the heavier bullet is more valuable than the higher muzzle velocity in terms of retained velocity and wind deflection at long range.

160amax in a 280AI, would be over kill, but is better than under kill!

im sort of the same way, i use the 175s smks in mine,group 1.2 " at 600 yards with good x-wind one day.(3 shots,with a sled)

did a test ,had 155s 168s and 175s all loaded up appropriatley(about 1 more grain of powder each lighter bullet weight),the 175s kicked they others bass.

plus dont the us marines/army use 175s SMKs? gotta be a hint.

since the above data,i have a match/custom barrell on with a 1-10 twist and its doing even better ,aside from the cold bore shot,it so far did .180" at 100/4 shots. and ive only had 60 first load development bullets down her now.

bottom line though is gotta use what the rifle wants to use.

I thought the Hornady 208 gr Amax was the bullet of choice for my Nemesis 308, after the tiny groups i got with the 208 gr Match Hornady, those are now the best ... 0.640 inch @ 300 metres, never tought i could shoot such a group, pictures of the targets on my tread... JP.
