Although I have not taken it on a hunt yet, I just picked up a used 7mm mag and shot a few rounds to try it out. Its a beast and acording to a little research, if I can aim straight, been told with the right scope can be deadly accurate up to 4-5 miles... ouch.
It would have to be an amazing buck to hike that far to find my kill, lol
But 1 can dream right? ;D

Note: The above ballistics chart depicts the Remington factory ammunition loading using just a simple core-lokt bullet that weighs 150 grains, while the ballistics don't look very impressive, this ammunition when used in 7mm Rem Mag barrels with a 1 in 9 1/2" twist carries a very high game shock value out to about 200 yards, which means if you shoot a deer within that range it will most likely drop right there on the spot it was shot and not move. Very good choice of 7mm Remington Magnum ammunition where hunting pressure is high, the woods are crowded with other hunters and you need to anchor your deer quick.
The 7mm Remington Magnum, Winchester Super X, 150 grain, Power Point bullet loading will react the same way as well.
