7mm rem mag VS 300win mag
 

Ok well I've gotta question I want a 300win mag and gotta chance to make a trade for one. I've got 2 3030's a 270 30-06 and 7rem mag the guy wants to trade me a identicle Remington 700bdl in 300 for my 7mag should I? Is there any gain in performance on deer? I also may hunt elk so what should I do

your call
 

How well do you like the 7 mag? Is it a good shooter? How bout his 300 is it a good shooter? Also are you guys trading scopes also?

There is no comparison.

The 300 has a wider range of bullet weights available, but the 7mm, loaded lighter, will fly flatter. Either will do what you need with midweight offerings in each. Since the guns are indenticle except for caliber, unless you're just wanting something different.....I would'nt change from what you have. I just don't think there is enough "practical" differance to worry about it.

IMO the 300 WM is way more gun than you need for deer, and won't kill an elk any deader than any rifle you have now. The shells, however, will be more expensive and you will notice the recoil more.

I wouldn't trade. Unless you just want the .300. For your purposes there is no real difference in my opinion.

I have both of them and from my experience you will not be able to tell which gun you shot the deer with. Both are very fine calibers with good down range ballistics. I reload my shells so there is not to much difference in costs. There is a difference in recoil, at least to me, I dont have any trouble shooting my 300, but there is a more recoil.
A 300 win mag is not needed for deer hunting, but I like shooting it. I glad that I have both.

For white tailed deer deer no need to trade. If you are into hand loading, the 300 Win. Mag. will give you a ton more alternative loads. I have a 300 Win. Mag. and love it. 200 gr. Nosler Partition ... sub MOA hand load ... 300-350 yard shots at mule deer were not a problem. Missed a badger at a ranged 455 by a few inches. Never hunted elk, moose or bears. I would think the 300 Win. Mag. would be better on larger game than the 7mmm Rem. Mag. It can handle heavier bullets. But just a guess.

I can't tell you what to do on the trade...but imo both are overkill for whitetails in most situations. If you are shooting 300yds plus as a norm, well a magnum will certainly fit the bill - and in that case, I'd take the .300 over the 7mm. More energy, more versatility.

Backwoods 7,
The 7 mag and 300 WM are really close in performance. Yeah sure there are more .308 diameter bullets rather than .284 diameter bullets on the market. But who really shoots all those different bullets? Most folks find one or two favorite loads and stays with them forever! My recommendation would be for you to pass on this deal. You already know what you have (in quality and performance) in your 7 mag; you don't really want someone else's problems!? Parting Shot: keep your 7 mag and buy yourself a .338 win mag for Xmas!!!
