I thik everyone agrees that the .300 gives slightly better performance energy wise than the 7 but for all practical purposes it's a take your pick kinda thing. As Major Calibre said, if you need more power than the 7 gives you, the .300 ain't where you want to go.
If you're just starting out, take your pick and join in this silly assed .270/30-06 argument that will never be settled. Or do like I do and own both and still can't figure it out.

I wonder where all this comparison crap comes from ?. .17 Fireball or .470 N E for prairie dog shooting ?.

I prefer the 7 Mag but am not going to use it on Cape Buffalo !. I've not encountered a single N A game animal that a " Well " placed shot didn't bring down ( I don't hunt Griz ) with proper bullet design and weight . Same could be said for 270 or 6.5 I guess .

I used a 7 RM for plains game in Africa it never failed me NOT ONCE !. I've seen 270 being used for the same purpose with the same result !.

A 7 Mag uses 100-180 grain projectile fast with plenty of energy . A .30 cal Mag. uses 110 -220 normally with the same credentials end results the same Dead is Dead .
It's a simple matter of " Personal Choice " !.
Nothing more nothing less .

Shoot Straight Know Your Target. ...

I use them for two very specific purposes.

My 7mm comes afield with me when I go deer hunting. I have a trim T3 Lite .270 Winchester that acts as my carry rifle for the lazy afternoons spent walking about tracking. My 7mm is a battered A-bolt with a 26" tube that is a freakishly accurate long range cannon. So it comes in the tree stand with me, ready to zap them peky deer from afar.

My .300 Magnum is my moose hammer, packing big, fat 200gr bullets for punching big, fat holes in big, fat animals.

They both have their time and place for me, I love them both!

.........There ain,t nuthin [FAT] about a 30 caliber bullet .....And there aint a thing the 300 will kill that the 7 mag won,t kill just as well ........It,s like people who use a 270 to hunt deer but carry a 30 -06 in case they run into a bear ...

I don't live or hunt in bear country, so I see no reason to carry more gun than I'd need. My .300 will drop 200gr Partitions into 1.5" @ 200 yards and my 7mm will do even better with 154gr SST's, that breeds plenty of confidence in those guns for their intended purpose.

Not like I have an opinion on the matter or anything

Paul..thats some mighty fine excretement stirring, now tell me what you really think!

Show me how you can tell one damn bit o difference givin same type components in a 7mm Rem mag 175 gr and the 300 Win mag 180 gr? Man I sure would not be able to tell and the animal hit in the same place with either cartridge would not as their terminal performance is virtually identical.
The bashing that goes on with the 7mm Rem mag just floors me. I have had both chamberings and I kept the 7mm Rem mag. Its been super for me and thats all a guy can ask. But I sure as hell don't think its superior to x number of other cartridges, but I don't have a 7mm bias or any other caliber either.

If a 7mm mag with a 175 partition at 3K is not enough for U, why stop at the 300wm, a .338 win mag is a hell of a step up from either, and if grizz is in your future, .338 always will have a lot of extra margin. Not to start another pissing contest, but I would wager that since hunting has began in the USA that the lowly .30-30 has taken more elk than all of them. Hell the .300 Savage with a 180 used to be an elk gun!

P.S. to the above. The thirty is most likely seen at more matches, because of better bullets. As for the military, the .30 has been the standard for over 100 years, so why switch now, and also see above about bullets!

I have had both like alot of guys. When I first got my 300 win recoil was an issue. I replaced the tupperware stock and added to the LOP. (15").Recoil is no longer an issue. Since then everything I point the 3oo win at just falls over when I squeeze the triggger. It has my confidence to my self induced range limitation that I am trying to extend with every practice session

I doubt that there is much difference, other than in the minds of the users, between a 7 mag and a 30 mag..or a 280 and a 30-06...all things being equal..

I personally like the 30 calibers in magnums..My all time favorite is the 300 H&H with heavy bullets.

As to killing power, what ever that means, I am not sure there is any difference between the 30-06 and any 30 caliber magnun..or the 7 mags and the 280 Rem...

The difference in the magnums is supposedly in trajectory and I agree that does exist, at least on paper, but how many of us can use the slight difference in the hunting fields is my next question.

I love the little 7x57 for an all around caliber for anything short of some DG...

Have both but for many years had a 7 for the light stuff and a 338 for the serious stuff...also have 264 and 300 and 375 just to round things off a bit...for the times that my 223, 243, 25-06, and 270, cant handle it...defines diversity for once in positive sense....

I guess I'm with Ray somewhat. Talking about thin-skinned NA game, it's more about distance and bullet weight than caliber. If you can get 140g to the whitetail you want to hit, going 2k+ fps it'll be fine, anywahere from .264-.358" in diameter. Figure the longest shot you're comfy with, and then find a bullet/cartridge combo that'll do that, and go.
Elk, make it 160+ grains and 2400 fps.

In 1969 my dad built a 300WM and I built a 7mmRemMag for an upcoming elk hunt. Although I agreed with my dad that his 300 was probably better suited for elk than my 7mmRemMag, we both agreed that either would suffice, and shot placement meant more than which of the two cartridges we were firing.

The primary reason I built the 7mmRemMag, rather than a 300WM, was the fact that I would be doing a lot of deer hunting and very little elk hunting. That made the 7mmRemMag a more versatile choice for me.

I used the 7mmRemMag for 20 years before picking up a 7mm-08 Mountain Rifle for deer hunting. I got to feeling a little silly using a magnum for hunting deer in the timber, while my brother filled his tags every year with a 30-30. My deer weren't any deader than his. Go figure.

I now have a .338WM for elk, and use a custom 7-08AI for deer. Even though I now also own my dad's 300WinMag, I consider it more of a tweener. It's more gun than I need for deer, and a little less than what I prefer for elk.

The 7mmRemMag is a fine cartridge, and if you are going to choose between the two, make your choice based on what you are going to hunt most.

My situation is more of a right gun for the situation than a right caliber for the situation.

Like I said, my 7mm is a 26" barrel heavy sporter that is an absolute tack driver even at long range. Shooting 140gr. Ballistic Tips across open fields is a no-brainer. I've hit my mark many times, out to just over 400 yards. But the gun must weight easily 12 pounds with a scope and bipod, not my ideal carry gun. So it sits in the tree stand with me overlooking the big fields. I carry a light .270 during the day for walking around. I could probably use the .270 in the stand as well, but my confidence in the 7mm is unshakable, and it will outshoot my .270 any day of the week.

My .300 is maybe 8 pounds and carries a 24" tube, the stock has a shorter LOP and a lower power scope. It has way more oomph as it loves 200gr bullets compared the the 7mm's love for the 140gr, but it not nearly as accurate as the 7mm. But it hits like no one's business. Several moose and one elk simply bang-flopped with it. Never took a step, just toppled over stone cold dead.

They're 2 specific rigs, one is a long range light medium game blaster that spends its time in a treestand, the other is a mixed terrain carry rifle for heavy medium game. It really has nothing to do with caliber and everything to do with the fact that the 7mm shoots light bullets at high velocities best, while my .300 shoots heavy bullets at reasonable velocities best. They sort of defined their roles for me. I'd certainly not have a problem using a 7mm for moose if the gun package was a little more wieldly.

Yeah, you .30 shooters stay away from all those puny 7mm Rem Mags. they are way to small for anything larger than a parakeet.

Saves them all for me!

One shot, dead Kudu 365 yards. One shot dead Wildebeest 225 yards. One shot dead Gemsbok 120yds. Yep way too small for Elk

Oh yes don't forget this 168 grain bullets at only 2990fps at 10 feet from the muzzle.

But you know what a 270win would have most likely worked just as well.

Shoot what you want to and what you like shooting and what you have confidence in.

My 7mm just happens to be the one rifle I shoot best and I just love to shoot the darn thing.

Yeah, me, too. I have a .300 RUM if I really want to loosen a filling or two. Kicks harder with 180's than my .375 H&H, but it will reach out and touch someone. I love the 7mm. Have used it in Canada, Texas, Alabama, SC, (where I do most of my deer hunting), and on plains game up to kudu and gemsbok in Africa, where with the 160 A Frame I got one shot kills out to 300+. I can't find anything wrong with it, but mine prefers the 160 to the 175. The caliber is a matter of personal preference, I suppose.

.......Mickey , I apoligize if I was offensive ,.,................................... I,ve reciently been embroiled in trying to talk some sense into someone who wants to come to my home area and shoot a bbb with a 300 .....I,ve had a bunch of 300 mags .,.because everyone said they were great ...or they were trades ect....I had 1, 7 mag .,.,It was one of the most accurate factory rifles I ever owned and I really liked it ...I really wish I had that rifle back but I have no desire for a 300 execpt as a blasting gun to burn the throat out of so I could send out the barrel and have it rebored to 338 and chambered to the RUM cartridge .......................I understand what you are saying about the different roles you use your different rifles for ,....I just flip out when soneone calls a 200 gr 30 caliber bullet both big and fat ....... A 600 gr .510 dia , Dead Tough Soft point is a big fat bullet ............

I own both the 300 & a 7mm. The 300 has more bullet surface and power then the 7mm has. The 7mm is a fine rifle tho I used it when I shot my boar. A boar running Full boar ahead.
