7mm mag vs. 300 win mag

I prefer the BCs of 7mm bullets and, thus, prefer the big 7. However, it ain't like either one can do anything the other can't. Just personal preference as I see it. My bud has a .300 mag, actually two now. He had a BAR for years in .300 and won a DU emblemed .300 as a door prize, a Mossberg in stainless with a laminate stock, at a DU banquet. I'm pretty impressed lookin' at that Mossberg. Anyway, he just likes .308 diameter bullets and I'm more into the better BCs and SDs of the 7. Either one has a huge selection of loads and components on the shelves. Ain't like one is the wrong choice and the other isn't. Both kill the same game and both will shoot about as far.

It does make for good campfire conversations. :D
 
From some forty years of reading articles about elk hunting with 7mm and .300 maggies, it looks like six of one, half-dozen of the other. There's not enough practical difference to matter. Not enough difference in the ballistics tables, either...
 
I agree with Art based on what I read when making the same decision a few years ago. I went with a 7mm Rem Mag as a deer/elk dual purpose gun. The 7mm Rem Mag will have less recoil and ammo is a bit less expensive.

The only thing that would push me to the .300 now is the wider variety of .30 cal bullets available for reloading, since I reload now. I would still go with the 7mm if I was deciding today.

Ya gotta talk about SOMEthing. At least it's not "what's the best deer caliber:.

So.. uh.. which .223 round should I use for deer at +300 yards? :evil:
 
Which is "better"?

Each cartridge is designed to shoot a different range of bullet weights, with a different diameter.

If you want to shoot a 7mm bullet, I have no doubt that the 7mm RM would be far more accurate than a .300 WM with the same bullet. 7mm bullets, at .284", tend to bounce down the barrel of a .300 WinMag.:p

If you want to shoot a .308" bullet, I have no doubt that it would be easier to chamber a .300 than a 7mm cartridge, with a .308" bullet in it!:D
 
Isn't there another identical thread in the rifle forum that the person who started this thread replied to in like the first 10 posts? I call plagiarism.
 
You will blow a bull elk in two with that magnum.
You can't kill that bull elk with that 308 @ 300 yds.
A 243 is good for anything on the NA continent.

Pick a rifle and go huntin', There is no verus or better than!!! They both work.
It's the nut behind the trigger that has the problem!!!
 
I was guilty of starting one of these threads a few months back when I was going back and forth between the 7mm and 300wm. In the end, I bought a Model 70 Featherweight in .30-06. Go figure! I have not had a need for it yet as my M70 .270 meets my needs just fine, but at least I can afford to fire my '06 a lot more than any magnum round.
 
the 7mm is supposed to be a little flater shooting, but i like haveing a better bullet selection from 30 caliber rifles. i also prefer heavier bullets for hunting game. paper is easy to put holes in, you dont need a lot of weight to put a hole in it. either will kill most things very easily, at least on this continent. but like i said, i like heavier bullets. i have never seen a 220 grain 7mm bullet.
 
It ain't bullet weight that matters so much as sectional density and the 7 does well against .30s on that. And, if You're shooting a 160 partition, you can kill anything the heaviest bullet can kill in a .30 caliber, so I don't see the problem here. If you really like bullet weight, you need to be shooting a Barrett or at least a .458. Or, how about a 12 gauge slug. They measure those in ounces. :D
 
7mag vs. 300mag is Coke vs. Pepsi considering most things we will ever hunt for. The numbers and personal experience say the modest energy and trajectory gains in the 300 over the 7mm might not be worth the not-so-modest recoil difference. I can shoot the 7mm all day and with the slip-on pad it's not a big deal, but my 300 really packed a jolt. And the cost difference was very noticeable, too. So I sold the 300. If I didn't have a 7mm already and wanted a beanfield/target gun I'd probably buy a 30-06. But I have a 7mm and love it. I hit a pig with a 150gr Federal soft point yesterday at 150 yards and it spun him around like a top. A 300 mag wouldn't have killed him any deader. A 30-06 wouldn't have left him less dead.

Coke ... Pepsi ... hell, man. Buy one of each. Guns are like guitars ... you can never have 'too many'. :)
 
Tell ya the truth, I really don't need the 7. I didn't have any real hunting rifle when I got it other than a .257 Roberts and I wanted something a little more capable for the mountains, big mulies at long range and the hope of an elk hunt some day. I really wanted a .280, but thought heck, why get a .280? I can't load it up, but I can match .280 with a 7 mag if I don't think I need so much power. Same danged rifle at the same price. Besides, I didn't own a belted magnum. So, that was my thinkin' process. .300 wasn't in my consideration at the time.

I later got a .308 Winchester and, tell ya the truth, as light and handy and accurate and easy to carry as that rifle is, and it has the power, I think if I ever did a mountain elk hunt, I'd pick the little .308. It's also nicer on my shoulder than my 7 despite being a very light rifle.

BUT, I ain't sellin' the 7. It's just kinda cool and I like it. :D I really see no reason to sell a good firearm just because I don't "NEED" it. :rolleyes:
 
i've killed deer and elk with 300 win mag, 300 wsm, and 300 rum (among the 300's). my son has killed em' with his 7mmremag. couldn't tell the difference. get the one that seems to fit you best.
 
I own both, a Winchester Model 70 in 7mm Rem Mag and a Stevens Model 200 in 300 Win Mag.

Both put any animal I have shot DRT 95% of the time, both have amazing accuracy and are flat shooting at ranges that a 30-30 could only dream of, and both beat the hell out of your shoulder.

I haven't reloaded for the 7mm Rem Mag yet due to the fact that I have enough factory ammo to last me another 3-4 years of hunting season. It's more of a safe-queen anyways since I bought my 300 Win Mag a few years ago...

As for the 300, I'm liking the 165 gr. GameKing loads I have made up to dispatch anything in the mountains of Virginia within 500 yards. Pushing a .308 dia 165 gr. pill at around 3,000 fps is very effective on critters. Not saying that a 140-150 gr. pill out of the 7mm Rem Mag traveling just a bit faster won't do it, I just like the extra mass to help push through both shoulders at 300 yards. This might change after I shoot up all of that $2 a shot 7mm Rem Mag stuff I've got and start loading for that....

Honestly though, no big difference. The 7mm's will have a slight edge on ballistics, especially after 500 yards over the .308 dia bullets. Both can pack a lot of powder behind the bullet too. Both are very effective and very versatile rounds.
 
I use my 7mm Rem Mag for deer, and my .300 Win Mag for elk.
Each one backs up the other if they go down.
They are both great cartridges for western hunting.
