why do we need the 7mm mag?

Recently acquired a 7mm Rem Mag. Got it in trade for my 357 with my cousin. I've been needing a good high powered huntin' rifle for some time and he threw in the scope and a nice sling and it's had less than 100 rounds through it so I figured, why not?
Looking at its performance, however, I'm a little confused as to why it remains a viable cartridge. it almost always drives bullets of an equivalent weight slower than does the venerable .30-06. When it manages a faster velocity, the difference is minimal, usually in the neighborhood of 100 fps; hardly a show stopping increase. Likewise, the amount of powder used to obtain these near identical velocities are almost always very similar as well, and in many cases the 7 uses less powder for a given bullet weight than the '06. This is in spite of the fact that the 7mm case is substantially larger than the aforementioned '06. what's the point of having a big belted magnum case and not using all of its capacity to drive that bullet to the limit?
So again, what is the advantage of the 7? Is it just the longer, thinner bullets and thus increased BC and/or sectional density?

Using your point, one could make the same argument against any other cartridge.
The .30-06 is the ultimate rifle cartridge.
Period.
Thank you John Browning !!
What an incredible intellect.
Doug
about lots of them. I guess it comes down to likes, and
dislikes. After all, with a 30/06, a 22lr., and a 12ga.
you could handle just about anything that you need to.
WOW I'm going to shut up now, that's starting to sound
like the gun ban bunch. revision: because the second
amendment says I can keep and bear it.
150 grain 7mm is higher than a 150 grain 308 and so on.

In a nut shell: The 7mm is needed because I have a Winchester Model 70 chambered in that caliber. After I sell this rifle the 7mm cartridge will have outlived its usefulness [;)]

This is essentially my appraisal of it as well.
thank you
algore-Went to the Barnes Bullet site and Midway sites. but could not find any 190gr 7mm or 250gr 308 . Please provide a link for these 2 bullets.
thank you
Don't know if they are still making them or not. These were the RNSP Originals. Some people such as myself hate to part with items we may need in the future.[:)]
We have the others because we want them, or someone tried to build a better mousetrap. Not that there is anything wrong with that.
If we had the calibers we just need, then there would be the 22LR, 30-06, 12gauge, and 45acp. I think those will do anything you want on this continent.

You are about right on here but just like cars people prefer different models/calibers. I personally do not see any need for the 7mm mag but the next guy might. As for cars, I do not see any need other than Fords but again the nest guy might see different. It is all about personnel preference.
I personally have killed more deer,hogs,bear with a 30-30 than all of my other guns combined. I live in SC and most shots are less than 75 yards. Now that same 30-30 wouldn't be much good out west where the 7mm has the down range advantage. I now use a 45-70 on most of my hunts but again most of my shots are less than 75 yards. I have gone out west and hunted Mule deer and Elk and I have a 300 H&H magnum for that type of hunting. I would prefer the 30 caliber over the 7mm mainly because I can shoot a bigger bullet and I have alot more choices as to which bullet to use. Of course I could do anything with a 7mm that I can do with my 300 except for the biggest of bears. I would not feel confident with a 7mm on the biggest of bears but with my 300 H&H I can shoot a 220 gr bullet at over 3000 fps.
it is the favorite gun from yotes to elk

And I have a 7MM WSM Model 70 Featherweight. My 2nd Amendment rights say that I have the right to keep and bare arms.
It does not say what kind of arms nor of what caliber.
Best!!
My 7mm mag runs a 150gr balisitc tip at almost 3200fps,.....never had to track a deer, even on 500yd shots.
As stated it kills the game. Plain and simple. I have used some of the short magnums when they first came out and talked to several people who used them for a short time and all have reported poor perfomance on game even though the paper numbers claim great performance. I don't know if they stretched beyond the perfect balance achieved in the 7mmMagnum or not but poor performers as far as taking game.
I will continue useing the 7mm magnum because where does a guy go from there?[;)]
