[QUOTE="entoptics, post: 1711640, member: 104268"] This statement is not true, except regarding recoil. The 300 WM and 7mm Mag have, for all intents and purposes, identical flight ballistics. The 7mm [U]does not[/U] shoot significantly "flatter" than 300 WM. With bullets of similar sectional density and B.C., the two rifles achieve nearly identical velocities. Individual rifles and loads may vary, but on the whole, the two are effectively the same for drop/wind when comparing apples to apples. For example: 7mm 180 Berger Hyb Target = 0.680 BC, ~2900 fps in 24" barrel 300 WM 215 Berger Hybrid Target = 0.691 BC, ~2875 fps in 24" barrel IMO, neither caliber is appropriate to use on elk at 1000 yds, unless you are an outstanding shooter, in perfect conditions. Even then, it's literally "marginal" by nearly all bullet manufacturers standards (i.e >1800 fps impact) For example, at 1000 yds, using a best case scenario with high BC target bullets, specifically NOT recommended by the manufacturer for hunting: 7mm 180 Berg Hyb Targ @ 2900 fps = ~1850 fps, 1300 ftlbs 300 WM 215 Berg Hyb Targ @ 2875 fps = ~1850 fps, ~1650 ftlbs 300 WM will give you ~15% more "killing power" at any given distance over 7mm Mag. This is just a matter of physics. Roughly 15%-20% bigger hole, 15%-20% more momentum, 15%-20% more energy, and of course roughly 15%-20% more recoil. [/QUOTE]
