Its said all the time, nothing new here, but sometimes its good to see.

Data is at 600 - 800 yards. Doubt I ever shoot game over 800 yards, probably much, much less, and under 600 it doesnt much matter among any of the projectiles considered long range.

In the charts:

6.5x47 Lapua and the 147 ELD at 2700 fps (conservative). Approximately 40 grains of powder.

280 Rem and the new 180 ELD at 2700 fps. Approximately 55 grains of powder.

300 Win Mag and the 208 Amax at 2950 fps (ouch). Approximately 75 grains of powder.


In summary, all have plenty of killing velocity at 800 yards. Windage at 800:

147 ELD 1.2 mils 35"
180 ELD 1.1 mils 30"
208 AMAX 1.2 mils 33"


147 and 40 grains of powder is most appealing to me. I believe we get hung up on extended range data, 1000+ yards, where more powder does matter, but in reality none of us will ever shoot at a big game critter at that distance.
