[QUOTE="Scot E, post: 642621, member: 10832"] I am a big fan of not overdoing it with magnum cartridges that aren't needed. Recoil is a much bigger issues when it comes to accuracy than most guys realize. But velocity IS a big deal. Using your example, the difference in the 208 Amax at 2440 fps vs 2900 fps (Win Mag velocities) is 3.3 Mils of holdover or 117 inches less drift at 1000 yards for the faster bullet. The faster bullet would also drift 16.2 inches less. Even at 600 yards there is 29 inches less drop and 11.5 inches less drift. A big deal which minimizes a lot of potential mistakes and errors. The other big benefit of speed when shooting the LR game is that it allows you to stay in the proper velocity window so you ensure your bullet properly expands. For many bullets this is around 1800 fps which the slower speed bullet drops below at about 550 yards. Of course the A-max helps with this because it will expand at far lower velocities than most other bullets but the point is valid for many shooters none the less. Also, I shoot 168 grain A-Maxs at about 2850 and am only 8.7 Mils at 1000 yards. Are you sure those numbers are correct? I ran numbers for the 178 A-max at 2650 and came up with about 10 MILS.
