7mm rem mag vs 30-06

7mm RM is an excellent cartridge but not up close. I think it's because it's too fast and the bullet doesn't have time to expand.

I know I have seen a very small buck shot at less than 50 yards in the lungs with 7mm RM run into the bush over 100 ft before it finally stopped. The exit wound was only slightly bigger than the entry. What would have caused this? I just assumed it was too fast. 162 grain hornady SST. I haven't ever taken the time to look it up. I love 7 mag.

A death run of 100 ft is a short one. You need to shoot a lot more animals before you start to draw conclusions about what works well, why it works, and what needs fixing. You need to re-visit your high school physics as well to help understand the laws that govern ballistics; internal, external and terminal. It may take some looking it up.
 
There biggest difference between 7mm Rem mag and 30-06 is that Remiington spent a lot more money on marketing to build the 7mm mystique.... :)

There isn't really a great difference using bullets of similar weight. They have about the same real world capabilities, on paper the 7Rem has a bit better reach and the '06 being better with heavy bullets.

Translation: 7mm rem mag shoots flatter and retains more energy at range.

These differences matter not within 300 yds,where most game is taken.

Anyone who finds the 7mag too fast is using the wrong bullets.

Oh, and the 7mag can shoot that new 195gr berger pill with a stupid high BC...
 
Since I started hunting in the early 1970's, I don't think I've shot anything further than 200 yards, so for me, anything the 7MM can do, the '06 can do just as well.

In fact, the 30'06 is capable of handling a bullet up to 220 grains, which makes it a bit more versatile.

Having said that, I do have two rifles in 7MM.

243win unsuitable for Black Bear, but the dirty 30 is good to go! lol

And 45-70 is ONLY suitable for Black Bear. You deer hunters need to quit using it, its not the right tool for the job! lol

And the 30-06 and 7mag aren't moose cartridges!

Can happen with a thick-jacketed bullet better suited for heavy game. Seen a Deer double-lunged at about 100 meters with a 250gr Speer Grand Slam bullet from a 35 Whelen which didn't expand well that ran quite a ways before piling up.

30 years ago when I got my first Roosevelt Elk draw it was fairly easy to convince myself there was a need for a 7mm Remington Magnum versus my 30-06.
Try as I might it became impossible to convince me there was any need under 300 yards. The elk fell to the 30-06 but discussion with a LGS owner in December 1986 made the 338 Winchester Magnum look like the answer. The Remington Classic for 1987 turned out to be the .338 so I ordered one. Load development produced some excellent results and with another LEH draw for 1987 the .338 produced a one shot kill.
That rifle over the next 15 years accounted for grouse, gophers, groundhogs, coyotes, deer, black bear and two moose. With the Nosler 250 grain partition and a maximum load of IMR4831 the velocity of 2750 fps produced just over two tons of energy. Many times I said if I could only have one gun it would be the 338. It eventually exceeded my needs and we parted company after securing a 280 Remington which is just a tad under the velocity of the 7mm RM.

Bullets failed to expand and "I lost that buck as the Barnes bullet just penciled right through" . . . use the eraser on that pencil and write in "Missed"!!!

i ve seen the first generation of x bullets not doing anything but pencilling. it was in 270 win and 7 mm mag it was with the small barrenground caribou and more than once on the other hand a 150 or 160 grains in partition always delivered ...

Yeah, except that the bullet weights are skewed in favour of the 7 Remmy. Use similar bullet weights and the difference is even less pronounced. :)
7mm 175gr gr and 30-06 180 gr.
7mm 150gr and 30-06 150 gr.

And just to keep it fair, compare advertised factory ammo velocity - and the difference shrinks again.

yet every post you make seems to be about BC?

I think you are mistaken. I'm a big fan of sectional density, (indeed its my go to number for comparing calibers usually) and velocity is pretty darn sweet too, but BCs are not the most important thing to me. Im not comfortable with shooting past 300m (and that's with a decent improvised rest) in a hunting situation so high BCs are just not required for me. I don't like really bad BCs though. Some 303 bullets are pretty bad...

I shoot a 270, a 243 with a 10 twist and a 303 brit. I'm the last guy to be raving over BCs alone. Now don't get me wrong, high BCs are nice and all, but a 150gr partition in my 270 shoots under an inch and the ballistics match my vortex bdc reticle pretty good too, so....

I love this chart. it's completely ridiculous, but it does show how ignorant so many hunters are of cartridges and bullets, and how often we see this sort of nonsense repeated on CGN lets us see who is actually a doer and who is a talker. :)
