User blog comment:Son of a Magnet/Magnum Ammo or Marksman Training?/@comment-1863708-20100822045341/@comment-2227334-20100822131913

The effect of Magnum Ammunition is much more straightforward: It multiplies the damage of each shot that hits by 1.25. With Magnum Ammo, the AN-94 would do 25-17.875 damage per shot (instead of 20-16.3). The M60 would do 25-20.875, and the MG3 would do 15.625-12.5.

At close range, this would mean the AN-94 goes from killing someone in 5 hits to killing him in 4; at long range, it goes from 7 to 6 (see footnote 1). The question now becomes: Would the shooter have missed one (or more) of those shots without Marksman Training that he wouldn't have missed with Marksman Training? Clearly, this becomes increasingly likely as
 * 1) distances increase
 * 2) bursts become longer
 * 3) the shooter is sidestepping desperately in a close-range scrap, but here there are quite a few other factors that come into play.

Obviously, the best way to find out which works for you is to try them both extensively, and use something like history page at bfbcs.com to give you some hard numbers (see footnote 2). I hope this will act as a guideline, though, and help point out what kind of things to look for when you're comparing the two during play.

1. This is all, of course, assuming the target has full health. If he doesn't, obviously the number of shots required to kill him with any given weapon in any given situation depends on how much health he has. Let's just say it's likely to require fewer shots. 2. Then again, BC2 is a game, and games are about having fun, so I suppose it's entirely acceptable to just pick whichever one you enjoy using more, even if the numbers say you're actually sucking harder. I turned off the crosshairs in CoD4 and W@W for this very reason.
