and about the distance, i dont know ive never been elk hunting. I dont really know what location i will be hunting. I really want this info because i dont know if i want a 300 mag or a 7mm.

We really could use more info,,,,but I have both rifles.
In my opinion try to get a .300 WSM in a 24" barrel. I have one in a new Sako Finnlite(23 7/16" barrel), and the felt recoil is about the same with a 165 gr Partition(moderate load) as my 7 MM mag with a heavy 150-160 gr load.
They are both great calibers..... with the emphasis on Elk I'd go with the .300 WSM.
