Brando 32, I see you are in Michigan, this means your hunting might be a bit close in for that long range beast. that is if you do not load it down.
my suggestion is multi-pronged.
shoot it for a while but down load it. work up to long range hunting speeds and weights. put a brake on it. you will enjoy it if the stock fits you. you will know immediately if the stock is too short. if too short have a gunsmith put a thicker butt pad and spacers on it.
now comes the big questions: what are your goals? Elk out west? Moose up north? Deer out west? deer in the brushlands? deer in the midwest? If you want an all around gun I might just keep that 7MM RUM and put a fast twist barrel on it so you can shoot the heavy slugs. then tailor rounds for where you hunt. high brush, load down a bit. run high energy heavy slugs for western hunts where you have long shots. I will give the devil his due, you have a case/round you can tailor rounds to where you hunt. after that; you have to make that beast comfortable to shoot, a muzzle brake, a proper length stock, good glass, a proper twist for the heaviest slugs you will shoot, set the level of potency for the game and the lengths of the shot you believe you will be taking. you have a versatile case/round.. use it to your advantage.
I have a 300 RUM I took in on trade as well. I already have a really good 300 Win Mag, actually two of them that shoot long distances well enough to not need the RUM. I am selling it to finance my 270-264 Win Mag build.
I hope this helped you.
