The 7-08 is .459" shorter (will work in short actions) and the bullet is .024" smaller in diameter.
 
The 30/06 is 18% bigger.

Based on case length, case capacity, average weight of factory-loaded bullets, charge weight, and bullet diameter.
 
.30-06--------------------------------7mm-08
150gr. SP-----------------------------150gr. SP
2950 fps------------------------------2650 fps
2850 ft. lbs.---------------------------2340 ft. lbs.

You make your own choice....

That's at the muzzle. The superior BC of the 7mm projectile will even that out further down the range and I would bet that at 250-300 the energy figures start to come together pretty quick.

I'm interested in why the OP wants to know how they compare sizewise.

Actually, 2,800fps is possible with the 7mm08 and 150gr bullets. Even with a 20"bbl.

In the real world, I can tell little difference between the two. Having shot over 150 deer with the '06, the first coming in 1976, the last, last season, and having shot over 40 with the 7mm08, the last two just two weeks ago, I can tell you that both are extreamly effective deer cartridges.

I actually now prefer the 7mm08. Even prefer it to the parent .308. Even though ballistic charts give the slight edge to the 7mm08 at extended ranges, switching to a heavier bullet with the .30/06 gives it the edge.

What Reloader22 does for the .30/06 and 180-200gr bullets, Reloader17 does for the 7mm08 with 139-160gr bullets.....
For game over 1,000lbs, the edge goes to the .30/06; for 585yd steel silhouetes, the 7mm08 is essentially unequaled.....
 
If you want a short action rifle with a round that can launch a high bc bullet and is capable of taking almost anything in north america the 7mm-08 is capable.
7mm-08 is the third most popular .308 based round after .308 and .243.
Size wise it is simply a 308 necked down.
7mm is approximately .284"
I wanted it for its slightly increased BC over .30 cal bullets.
I really wanted 260rem but it is such a poorly supported cartridge and really not up to the largest of beasts roaming north america.
270win is a 30-06 necked down, has good BC and range but i wanted a short action rifle that i could convert to use detachable magazines.
 
7mm 08 all the way. While .260 is not gonna be as popular bec you already have the .2506 for more than half a century. And the 6.5 Swede crowd will not back down as they are first .

I don`t think the difference is arguable 7mm-08 is .420 & the tried and true .30-06 is .417 I think I will keep my 06...... Don`t tell me I don`t know the diff, been doing this over 40 years.
 
Heres what i have now for my daughter and son , and my son started shooting at age 8 then progress to bigger calibers,

BB s toy

.22 LR

7.62 x 39

5.45 Russian

Maybe i ll let him try the Garand and Finn M 39 once he gets into High School.

I've heard a lot of people debating these two lately and was simply curious.

WOW! So, when someone simply wants to educate themselves, they shouldn't ask questions? Got it. You're right, I probably don't have the experience with rifles that a tenth of the people on here have. But, I'm willing to bet that when they first started that they didn't know everything there was to know.

I appreciate all of the replies that were actually helpful and answered the question.
