Traditionally inaccurate cartridges

[Cervus elaphus]

Many cartridges are not considered very accurate by many because of their history as traditional hunting cartridges. Such as 270, 30-06, 7x57, 257 Robb. And many dangerous game cartridges.
What guns do you all have that disprove these claims ,and show groups too if you can.

In the late 1950's in NZ, two very common calibres sold were the .270 and .30-06 both very accurate. Who are these "many" ? think we can rule out NZ, Australia, USA, Canada, South Africa and other lower African countries, so do the "many" come from Europe?

This thread should have died 5 days ago.

There is nothing inherently wrong with the accuracy of any of the cartridge's mentioned.



A cartridge won't last 100+ years or so, if there is something wrong with it's accuracy on the platform in which it was intended.

I'm sure there are many cartridges that are "hot" right now, where factory loads will not be available in 25 years.



Does anyone know where I can get a variety of new factory 243 WSSM loadings to choose from?

I don’t think I’ve ever heard of the 270 being described as an inaccurate cartridge. Quite the opposite I’d say….

270 Win, 280 Rem, and 7x64 Breneke....very similar, and are considered accurate hunting rifles in most hunting circles...

Or maybe Bob's .25 Samurai? .25-7.7 Jap. More powder capacity than the .303.

I Believe the case capacity is 65 grains of rice, safe if used on a Arisaka 99 action .
My father who fought the japs in the Pacific use to tell me about the 6.5 Japanese in the mod 38 rifle & its ability to shoot through palm trees. so the Japs really invented a 6.5 CM type cartridge in the 1930s. As did the Italians with the 6.5 Carcano.

John, I think many of us are noting what was asked.

Are there any cartridges that are generally known for poor accuracy?

Not that I know of.
Many have the ability to be great in the right platform.

Are certain rifles inherently "inaccurate" Yes, cheap and nasty ones. Generally speaking

The "right platform", such as barrel length and twist, and the weight of the rifle, as you said, play a huge role in the accuracy of a rifle.

@rdog
Is that 65gns of rice short grain, long grain, basmatti, brown or white.

Well Bob’s Samurai can shoot through eucalyptus trees at 600 meters. That’s mostly what he hits when shooting at game anyway. So, the Japanese 6.5 was/is nothing special. LOL

Varoius 6.5 have extreme ratio between diameter and length of bullet.
Thus, they have very high sectional density, and theoretically (with pointed or hollow point bullets) extremely high BC for caliber. For this reason in hunting applications they will also have high penetration.

On the other hand, various .30 cal bullets are short compared to their caliber, and for this reason have smaller potential, and in accuracy department (ie - long range accuracy), they are loosing popularity while various 6.5 are gaining.
The only reason for this, is (obsolete) SAAMI and CIP specs for 30 cal, defining LOA and chamber dimension specs for calibers such as 308 win, 30-06 etc.. The standard accepted by industry for last 100 years, and hardly can be done something now to change.

.30 cal (like 308 win) now is in long range shooting mostly kept alive because it represents class of its own (F class FTR) and is coming from nato standard. And they are well proven in hunting fields, but there, in hunting, perfect accuracy is not required.

Below are some older examples with long for caliber bullet visible in 6.5 mm class. At least to me, the lenght of bullet sticking out from casing is impressive.

6.5x55
Arisaka 6.5

but i have too many gun now.

I thought I had a good command of the English language, and I do know what every one of those words mean, but when you put them together in that order, it just makes no sense to me whatsoever!

I think i promised my wife this was my last gun about 5 guns ago, & i need a bigger safe now . getting one would risk ending up like , what was his name Bobbet or some thing ? getting it cut off whist i was asleep

Spot on i am a 6.5 fan 6.5x55 x2 , 260 Rem, 6.5 Grendel .& do not tell any one a 6.5 CM.

I have 6.5 Grendel, 6.5 cm 3 260 rms, 6.5x284, 2 264 wns and 6.5x300 wby. Sill need a 6.5x55.

@Flewis
I don't see any 25s in there my son but I do see a man bun. Shame shame shame.
Ha ha ha ha

[rdog]

I feel better now may, be a Ruger no1 30/30 & a 22 hornet & Marlin 25/20 would really fix me up. Or a 257 Roberts or 25/ 06 or a ---------------. Or a chronograph like 35 W Bobs that displays what you wish the speed was! no offense Bob as i am only kidding.

Have 2 25:06s, and a 257 bob. That should count in my favor.

@Flewis
It does a bit but the 6.5s still out number them.
A nice 25-45 sharps in an AR platform. Almost the equivalent of the the 25 Savage and a nice 257 Weatherby would do you nicely.

I have been looking for the right 257wby. I need another 250:3000 and 25:35.

A 25-45 sharps almost equals a 250 Savage with 28gn of powders.
Would be nice in a little 6# rifle.
