What constitutes “inherently accurate “?

[Big Cherry]

i see this phrase slung around for certain cartridges but what attributes or Ballistically makes a cartridge inherently accurate?

I dont believe there is such a thing. I think there are cartridges that are more efficient and easier to load for and get better SD and ES, but they can all be accurate if built correctly.

I'll second that!

Some cartridges are just easier to find an accurate load for than others, even in identical rifles. Those are the cartridges I think of as inherently accurate. Some that come to mind are the 6.5x47 Lapua, 6.5Creedmoor, and .308. Not to say you can't make other cartridges shoot as well, but for me it takes more rounds fired in load development to find a load that shoots as well.

There will be plenty of folks that say there's no such thing as an inherently accurate cartridge. If that were so, you'd see something besides the 6 PPC winning benchrest, but you don't. It wins because it is easier to find a winning load for than any other cartridge currently available. Folks will come up with a myriad of reasons of why that may be so but the simple fact is the BR guys could use any cartridge they choose. They all use the PPC because it increases the odds of winning. The PPC is inherently accurate and there are other cartridges that are as well.

Really should be applied to the guns themselves or barrels etc and the companies or individuals who make them...not cartridges.

Cartridge design does have a bearing on how accurate they "can be", but most if this is because of many other things like the chamber, barrel ammo and the shooter.

If the right combination of all things are done, any cartridge can be accurate. Some are just easier to reach that accuracy than others. The cartridge case is just a container for the powder, what is done to this case and chamber can have a negative effect on an otherwise good cartridge.

The most noticeable example of this difference is the efficiency of some designs that are able to reach the same velocities of other cartridges with less powder. this sometimes contributes to the term inherently accurate because they may be able to work up loads for.

This efficiency has been discussed many times on this site to explain things like Flame front, burn rates, case density and many other things that can make a cartridge perform better with a certain set of components.

There is no doubt that some designs are easier to find a good load for, but does that make them inherently accurate ? or give them the ability to become accurate with the right combination of parts and components ?

Notice that the BR cartridges are shorter, fatter, WSM style and most are just easier to tune, have much wider nodes(hence they stay in tune better in changing conditions), and aren't as finicky as other designs.

There is something to design, be it shape or just hitting the right capacity. Like what has been said short range BR is dominated by PPC, in two years the 6BRA with the same shooters have destroyed records from the Dasher, like a lot and the only difference is the cartridge.
I think there is something to design I also think it's hard to put you finger on the exact attribute that brings it.

I'l go with that, because every Creedmoor Chamber IS accurate. Mass produced accuracy. Don't hate the playa, hate the game!

There is NO such thing as inherent accuracy when it comes to firearms...Period...Full stop.

I was waiting for that

The 6br and variants are inherently accurate. It's pretty undeniable. Look at the benchrest cartridges racking up wins and records. It's sad but cartridges like the 6.5x284 is all but dead in 1000 yrd
Benchrest competitions. The 6 dashers and 6bra s Are the way to go. And it can't be dismissed as a fad since they broke the hell outa the previous records. Look at 100 and 200 meter competitions. The 6ppc has ruled the ranges for years. It's just inherently accurate.
