Mtboy go to www.federalcartridge.com. Compare a 220 gr speer hot cor SP for an 06 and a 175 gr Hi-shok SP for a 7mm. The 7mm has a very sizeable advantage. At 300 yds the 220gr bullet has 1300 foot lbs of energy. At 500 yds the 175gr bullet has 1370 foot lbs of energy. Also look at the trajectory of the 2. Compare bullets of the same weight and you will see the 06 actually has a little more energy out of the barrel and up to about 100 yds. After that the 7mm has an advantage giving you a flatter trajectory and more range. It carries its energy better than the 06 down range.

Mtboy- Your assumption as to sectional densities is wrong.When penetration is concerned you must consider sectional density(with bullets of the same construction) as well as the fact that the 7mm makes a slightly smaller hole.Combine that with the extra energy of the 7mm mag and the fact it holds its velocity better at longer ranges and the 30-06 will not provide as much penetration as the 7mm mag.When using the 220 gr bullets youb will also get a great deal more bullet drop than with any 7mm load.Once you have gained some ballistic experience and taken a fair number of game animals you will also see the difference between theory and what actually does happen with different bullets.As to the big bears you talk about just how many grizzlies have you taken?

Stubble - if you look in my earlier post, my idea was to carry a 220 grainer in the chamber for close encounters with big bears and 180 for the rest - I still will. I never paid much attention to 7mm's but I have more respect for those varmit slayers now - thanx! <img src=icon_smile_wink.gif border=0 align=middle> You've convinced me...my next gun will be a 300 or 338 mag... <img src=icon_smile_blackeye.gif border=0 align=middle>

I have shot five grizzers so far - one at 30 yards a few years ago, and this year - three at 150, and one at 300 (all with my camera) while hunting blackies. I don't think I'd want to shoot one with a gun, 'cause I don't think I'd want to eat it... My neighbour did get chewed by a big grizzer boar last fall just up the road, and one was hanging around just up the trail this summer... anyways, bears aren't that hard to shoot, unless you use a bow&gt;&gt;&gt;next year!

I't always interesting to take off on tangents and split hairs when discussing the merits of diffrent cartridges. However the original question was not &quot;which will flatten a griz faster?&quot; or&quot;which will ventilate a pronghorn in the next county?&quot;

I have never taken a head of game with eather but from what I have heard and read of both, you could flip a coin and not be too unhappy with a custom rifle in eather round. As some have said the 06 has a bit more variety in bullet selection for reloading. And you are more likley to find a box of ammo in a small town hardware store or service station.

To get away from the paramitters of the question a bit; if I were going to have somthing as exotic as a custom rifle, I would probably want it in a somewhat more exotic cartridge. A 208 rem. or a 300 WSM or a 7 X 61 Sharpe & Hart or a .35 whelen.

Splitting hairs, huh? I knew someone would misread my last post so let me clarify. 220gr 06 vs. 175gr 7mm mag.

Muzzle 300yds 500yds (Energy in ft lbs.)
220gr 2835 1300 760
175gr 3180 1960 1370

Trajectory(200yds) 300 yds 500yds
220gr -13.1 -82.2
175gr -7.6 -44.9

Hardly splitting hairs, big difference. So to answer the original question, I would go with the 7mm because it's more gun.

Tell me more about the 300 WSM, that's the one that interests me, or should I start a new thread.
Recoil, trajectory and bullet options for North America applications, or if you like compare to 7mm R mag.

I guess &quot;splitting hairs&quot; was a too fine a distinction. Splitting match sticks? or splitting pencils? or splitting broom sticks? There is a diffrence between the 06 an 7mm mag. for sure. But a moose, elk or deer hit through the chest at even 300 yds. with eather round is not going to be aware of which penitrated it faster or deeper or with more ft/lbs.

So I guess we could say that beyond 300 yds the 7mm mag. shows off some more muscle and would have an advantage. Shots passed 300 yds. are possible but made more often on paper than in the field.

I'm not saying anything negative about the 7mm mag. It has a HUGE advantage over a 30/30 or a .243 or a 257 roberts for moose and elk. But the advantage over the 06 is just not that huge in my view.

skeeter 7MM

I got a question. Tell me of the 06 users how many chuck 220 or even 200 gr bullets? I know many guys who use this caliber and most commonly chuck 180 gr at big game and 150 grain at deer. Most of the guys that like chucking the 200 grainers opt for magnums or big guns suchs as 300 or 338's.

If you say i use 150-180 grain bullets, ain't nothing an 06 will do that the 7 rem mag won't do better(numbers show this). That being said they will both still kill the game, it's opinion and preference.

If you want to chuck the big lead, leave the 06 on the shelf and go with a biggun...not just b/c it fires 30 cal bullets that will afford you 220gr bullet...but no real advantages over 175 gr 7 rem mag or 180 gr 06'. Just my lame a$$ opinion.

Actually, thinking about this, you should compare apples to apples. If you take the 7mm vs the 30-06 & the 300 mag. vs. the 7mm mag. Now, more accurately, the .308 caliber beats the 7mm all around the board...

Check out these numbers:
Energy at: 100 200 300 yards
300um/180gr 3686 3201 2786 ft/lb
7mag /175gr 3187 2718 2313 ft/lb

AND you have the greater bullet selection of the .308... <img src=icon_smile_big.gif border=0 align=middle>

The thread was comparing the 30-06 to the 7mm rem mag so what has the 300 um got to do with this comparison.The other problem is that most hunters can't shoot the 300um accurately due to the recoil while the 7mm mag is quite tloerable by most shooters.
