losthwy, according to the majic formula of 2000 ft lbs to kill an elk, my set up (150gr partition handloads) has enough to kill an elk at about 350yds. At 300 yds it has over 2100ft lbs. I disagree with the 2000 number anyway, in my opinion its closer to 1700 or 1800. At 400 yds my bullet set up is a little over 1800 ftlbs. I'd say if you want more range change your set up. There is no way anyone will every convince me that the 7mm mag is only effective on elk up to 250 yds. Too much experience that says otherwise.
