Ballistically they are quite similar. The 300 Rum (or any of the big 30 cal magnums) pushing a 240 gr VLD is quite a good long range option.

The 338 Lapua does best with 250 to 270 gr bullets, although the 300 gr SMK is a serious contender for long range accuracy.

BTW that 2,400 meter shot taken with the 338 Lapua only has enough dope on the S&B PMII scope to get out to 1800m of drop with the standard Brit sniping load. Which means that the angle of the shot needed to cut 600 meters of the shot length, meaning the angle of the shot was around 42 degrees. 2400 line of site distance * cosine(41.4) = 1800 meters of drop.

Here in Afghanistan there are some pretty tall mountains...

Anyways most of us don't have access to ranges that can make use of the ballistics of ANY of the magnums, even a 300 Win Mag pushing a 190 or 220 SMK.
