I just bought a 300, I looked at the 7 and researched my realoading books and found the 300 to be slightly better in speed and power but not enough to make a differance. Both have enough power for anything in North America.
 
Both are great rounds, sold my 300 because of recoil, still have my 7mag but the older I get the more I like my 243.
 
Still loven the 243 but started shooting the 300wm 4-6 years ago & love it.been carrying my ar to shoot a deer to make sure grand kids wont loose a deer.may take the 300wm in the am
 
9 times out of 10 when I walk out of the house to deer hunt with a rifle I have either a 7mm rem mag or a 300 win mag in my hand.

My 300 is my favorite rifle.
She is like an extension of me. When she makes noise, stuff dies, simple as that.
Her name is Diana.
Browning A-Bolt with a 3-9X50 Leupold varix II.

MOST of the time, if I can get my sights on it with that rifle, it dies.

With that being said, from my experience from killing a BUNCH of deer, the 7mm mag does more damage to a deer than the 300 does.
It is like until you get out to 250+ yards the 300 just don't get going good to just really pound the deer. However, I don't guess it matters what kind of damage is done when it hits them and they drop where they stand.

Couple of other things.
I shoot Remington Core Lokt ammo out of both. 150 grains, from wal-mart. I don't reload and ain't gonna spend any more than I have to for shells.
Their accuracy has been more than acceptable and out of my 300 it is a friggin tack driver.

I also aim at the center of the shoulder when straight broadside and if not, or if I am in a good mood, I go for the high shoulder / low neck shots.
Complete, total and immediate shut down of all communication.
When I am shooting a centerfire rifle I am not a fan of blood trails.
Bang / flop, go get the deer. That is how I like it.

I don't care what kind of high performance sports car or jacked up four wheel drive you got, if you rip both front wheels off, it ain't going far and however far it goes, it will be easy to follow. :D

Since you asked, there ya go and in the words of Buckwild, YMMV :D
 
Ruger's post is the best one on this thread. I share a lot of similarities, except I shoot a 7mm Rem mag...never have shot a 300.
 
I am probably going to order my 300wsm tomorrow. I do load my own stuff and my research tell me this is a great round. My 308 deal fell thru so this will be its replacement. Browning abolt.
 
Both are unnecessarily powerful for a deer but if I had to choose, I'd go with the smaller of the two and take the 7mm. Most guys that have either one of these would shoot better if they had a smaller rifle that kicked less. And just because you can stand it and shoot a whole box of ammo at a sitting doesn't mean you are shooting with the best accuracy you are capable of.

I have a 460 Weatherby that shoots 500gr bullets at 2,600+fps and I can certainly shoot it a bunch in an afternoon but I can definitely shoot a lot better with my 25-06! :)
