[QUOTE="wildcat455, post: 1662689, member: 102653"] I'm totally biased. I've had 300 win mags for over 35 years. Currently own 5 of them, all in different configurations. Crunching numbers: I have a 215 gr Berger HT load for 4 of my 5 rifles that hover right at 3000 fps. (Give or take 50 fps total, or +- 25 fps, depending on the rifle.) Using the 3000 fps figure for speed, that right at 4300 ft pounds of muzzle energy. That gives about 2300 fps and 2600 ft pounds of energy at 500. At 1000 yards, 1763 fps and 1484 foot pounds. I don't load for 7 mag, so these numbers may be off. A 180 gr Berger VLD H at 3000 fps (this is the part I don't know, can they be pushed faster accurately and not over pressure?) You have 3600 ft pounds of energy. At 500, 2274 fps and 2066 ft pounds at 1000, 1663 fps and 1105 ft pounds energy. In this example, The 300 WM gives more energy, 700 ft pounds at the muzzle, 534 ft pounds at 500, and 379 foot pounds at 1000. Couple things, the 7 mag will shoot nicer without a brake than the 300. The trajectory may be a little flatter and wind may be a bit better with the 7 mag, but you're already dialing at range, so what's a few extra clicks? Wound cavities will be better with more bullet at speed to make them. You definitely have enough gun to take elk sized game at 1000 yards with the 300 loaded as above. With a brake and a 10-12 pound rifle, the 300 win mag isn't too bad to shoot. If you're hunting, it matters less because you'll be shooting less you won't even register the recoil. If you aren't hunting, brake and heavy rifle (12-15 pounds) and you'll be able to be behind it all day. At the ranges you specified for hunting, either cartridge will do. You may not have the expense of muzzle braking the 7 mag, you'll just have to shoot it and find out. [/QUOTE]
