Todd, I don't recommend large mags for deer because of a desire to increase the bullets energy. It's simply all about velocity. And to get it there quicker and flatter it has to be started out faster which DOES result in more recoil, noise and expense. I agree too that for the most par there isn't enough difference (trajectory wise) between a 30/06 shooting 150grns vs a 300WinMag shooting 180grns to merit switching one for the other with concerns too deer (yeah I would MUCH rather have the later with something larger than a caribou is the target). I am talking about taking the same bullet from that 06 and increasing its velocity by 500-nearly 1k more fps and THEN you see quite a difference in trajectory. In my mind (and my own personal experience) it is MUCH easier to hit (with great accuracy I might add) at 400yds when the bullet is only going to drop about 3" vs a foot and a half in the 06. I know it because I do it with regularity and I have done it with both.

As for the comparison you gave, I would like to see the test had he used a true supermag vs that 308. A faster bullet does two things, not only does it drop less but it also drifts less in the wind because it is in flight for a shorter time so the wind has less time to grab that bullet.

Now what does all this have to do with my original post?
