theoretically, which one is inherently more accurate? 7mm mag or 30-06?

In equal rifles with equally consistant ammo, I doubt if you could tell the difference. There might be an argument supporting the 7mm as more suitable for long range, but not more accurate.

I have a 7mm Rem mag that is more accurate than any 06 i have seen but it is a custom built rifle by Bill Leeper. In factory rifles i have owned both and they are both the same in my opinion except with lighter bullets the 06 might be a little easier to find a load that is accurate as they can shoot alot more varieties of powders over the 7 mag.
everything being equal, my bet would be on a 30-06
of the rifles Ive owned, the 30-06 has shot better for me, and thats a Sendero SF 7mm Mag vs a Titanium 30-06!
at longer range, 500+ yards, I think the higher BC & velocity of the 7mm bullets would turn the table

The 7mmRM case has been noted for larger than average pressure swings.That is why it has been downloaded to meet the tight SAAMI specs when they started testing with gauges.I don't think that helps accuracy.It also burns more powder.
What does the BC or the velocity, in this case,have to do with accuracy?Either cartridge is going at supersonic speed and the BC of the 7mm is not that big of a difference compared to .30cals.The only thing that would turn the table at long range would be the shooter behind the gun,me thinks.todbartell said:
30-06 Headspaces on the Shoulder......
7mm Magnum on the Belt
In 2 Identical Rifles I'd bet the 06 may have a slight edge...in theory anyways!
But WHO really can shoot well enough to Notice a Diff in MOST Hunting rigs ?Both Cartridges are easily capable of MOA or better in Good Rifles

compare wind drift in a 10 mph crosswind at 1/4 mile between a 7mm 160 gr Accubonds @ 3000 fps vs 30 cal 165 gr Accubond @ 2800 fps
Id guess the 7mm would show enough of an advantage that if all things are equal (shooter, rifle quality, load quality etc), that the 7mm would be more accurate, as there would be less variation from shot to shot in the varying winds

Got 2 1/4 in the hor. and 1 1/2 in. in the vert @ 500 meters for 5 shots with 7mil mag and 168 match king
Yes I know............varminter said:Just headspace the 7mm Rem on the shoulder as well.If you shoot for accuracy,then that's the way to do it.
Trouble is MOST Hunters buy thier ammo from the Store thus "Fire formed" brass and Neck sizing tricks are "not the norm"
How so?todbartell said:
If you know how much your bullets gets moved at the given wind condition,then it really does not matter,wether i crank the scope 4clicks or 8 clicks.
The variation from shot to shot are the same,just a wee bit more with the 30cal.I don't think,that under normal hunting condition,you can't tell much of a difference.Forgive me for splitting hair.
what the wind is doing at the shooters position, its speed at the target, and the speed halfway, arent always the same thing! the less the bullet is effected by the wind, the more accurate it will be at longer ranges. between the 7mm Mag & 30-06, the 7mm Mag has a higher downrange accuracy potential
It has more to do to with, how good you can estimate the varying winddrifts than the accuracy potential of your gun or cartridge.todbartell said:
Because the 30-06 drifts a bit more at a given wind,does not make it less accurate than the 7mm.
