[QUOTE="benchracer, post: 1044972, member: 22069"] Using your numbers, at standard temp and pressure, with the Berger 300 EH and the Berger 230 Hybrid, JBM produced the following: 600 y 300 EH 1823.6 fps 2215.0 ft/lbs 16.7 MOA drop 3.1 MOA drift 230 HYB 2172.7 fps 2410.4 ft/lbs 11.3 MOA drop 2.6 MOA drift 1000y 300 EH 1482.1 fps 1463 ft/lbs 35.7 MOA drop 5.7 MOA drift 230 HYB 1764.6 fps 1590 ft/lbs 24.7 MOA drop 4.9 MOA drift The .300 Win Mag beats the .338 Win Mag in every category. The gap doesn't narrow, at any point, all the way to 2000 yards. An .8 MOA difference in wind drift is equivalent to more than 8 inches @ 1000 yards, enough to move a hit out of the vital zone with a small error in making the wind call. 11 MOA @ 1000 yards is more than 9 FEET of difference in drop. That may not matter as much if shooting steel or paper on a known distance range, but it dramatically increases the difficulty for shots in the field, while reducing the room for error in range or wind calls.
