That's just because of the rifles available. I've seen a 7.62x39 that would shoot as small of a group as the shooter was capable of.
For example, 6mmBR = inherent accuracy, 7mm STW = inherently finicky. FWIW, most decent 6mmBR rifles with a 1 in 8 twist will shoot a 105-107 grain bullet over 30.0 grains of Varget very well.Some cartridges have a design that gives a more even, consistent burn with a wider range of powders. Usually, the shorter & fatter powder columns get more uniform ignition and burn than the long skinny ones.
Lots of gobbledygook getting thrown around here. If you build the rifles the same way, load the ammo the same way, and use the same quality of components then it won't matter what cartridge you shoot.
Nobody is going to win a brenchrest competition using precision rifle shooting specially made ultra-high quality .30-30 cartridge.
Nothing would stop you. Other than the lack of truly high quality brass. You could make up for that with proper prep though.
If that were true the .222 Rem would still dominate Brenchrest.
That has more to do with fashion than anything else.
A better question would be what makes a cartridge inherently INaccurate. There are few, because normal testing by ammunition designers and makers will weed them out before they reach the market.
But a poor bullet shape, poor bearing surface in a barrel, wrong choice of powder, lack of adequate power/velocity, poor sectional density, can all mean a cartridge that is inherently INaccurate. There are few factors that can be isolated to the cartridge alone; most involve some firearms factors as well, like rifling twist.
Many of the cartridges considered inherently accurate should not be. There is little about a .38 Special Wadcutter that is "inherently accurate", yet with years of development for a specialized game, it is the choice of bullseye revolver shooters.

I think it is a relative term - heard it first in relation to 30-06 vs 308 - at some point 308 started winning more matches and folks concentrated on 308 with the argument that 308 was inherently more accurate.
I'm really curious why.
