The 7MM Rem Mag never made a lot of sense to me.

For long range deer, I use a .270 Win. Less recoil, just as flat shooting, and kills deer out to 500 yards like lightning. I won't generally take shots longer than that.

For elk, I use a .338 win mag. Not as flat shooting, but delivers lots more foot lb. If you ever aspire to hunt large bear, this is your cartridge. Most of the elk I have seen wounded and not recovered have been shot with a 7 Mag.

I guess if you were looking for an elk rifle and never wanted to go bear hunting, or you wanted a bigger bear rifle like a 375 H&H, the 7 Mag might be a good choice.
