Hornaday is at it again... This will keep the fan-boys running back for the latest/greatest. .25 CM

Any of the New Creedmoor based cartridges are Great - just that the 25 cal is severely lacking on a good choice of Bullets YET 🤷🏼‍♂️. RJ

Hopefully SOON - Hornady will reintroduce the “ 30TC “ as a 30 Creedmoor and neck it down to .284 also for a 7 mm Creedmoor 👍 those 2 cartridges are widely needed . 🤣 RJ
Are you sure you are not already on their staff?? LOL
 
Do the older 257s have a fast enough twist for the heavy bullets? Or is it pretty much a custom build only option?

Like the 6 CM, it seems this is what would be alleviated....as well as fitting inside a short action. If you don't mind going custom, doing the handloading, and do not care about having a long action, obviously this cartridge will have no appeal.

Besides perhaps cheaper brass.
Early 257s from the 250-3000 and 257 Rob days started life with 1-14 twist rates. I had a Remington 721 chambered for the 257 Rob with a 1-14 twist and it wouldn't shoot anything heavier than 100 grain spire point/flat base. I believe most 250 Savages are still made with 1-14 twist rates.

However, Remington fixed that issue several decades back when they produced the Model 700 and adorned it with a 257 Rob with a 1-9.5 twist rate, that will handle bullets of any shape up the heaviest available 125 grain spbt.

Why not just stick with the proven and venerable 7-08????
 
It's basically a 257 Roberts in a smaller package. It's also designed for higher pressures.

The 257 Roberts, when loaded to similar pressures in modern rifles will beat the 25CM, but not by much or enough to make a difference for hunting Deer and Black Bear size game animals.

The 25 cal market is not huge, mostly due to a lack of interest.

Most folks I know are blinded by the velocities which can be achieved with lighter 75-100 grain bullets. However, when the 115-120 grain bullets are loaded, the 25s really shine.

If you thing the 6.5CM generates light recoil, the 25 will be even lighter, with similar accuracy and field capabilities, when good bullets are used.

My only concern would be for those who don't handload. Finding LGS or even Big Box stores which carry commercial loads could be difficult.

I have a friend who was talked into purchasing a rifle chambered for the 6mm ARC. Beautiful rifle, extremely accurate, "if he can find ammunition"

He's not the type to purchase more than one or two boxes, so it's a constant issue for him when he's looking for ammo.

These cartridges are floated regularly but often don't last long and become "hand loader only" safe queens.

Many of the rifles I've torn down to build custom rifles were chambered for "flash in the pan" cartridges and sold to folks who only shoot factory ammo.

This should be a consideration for anyone looking to get into this as a cartridge of choice.

That being said, try finding an LGS which stocks a good selection of 257 Roberts or 25-06, which will perform as well as the 257CM will with factory loads.

IMHO it should be a great little cartridge, with great potential, IF you handload.
Meanwhile I'm sitting on a pile of 6 arc ammo and components, with nothing to shoot it with as i cannot find the rifle i want....

Oh, thats good. Opens up some options for sure.

Thinking the 25 CM is going to be loaded with stuff like the 134gr ELDM, or Berger's 135gr Long Range Hybrid BC of almost .65, Hornadys 138gr A-tip, .695 BC etc
 
You really don't like new cartridges do you Meroh haha.
Well, if it actually did something new, then it would be notable.

Well, at least they did not call it a CM. The 6mm ARC actually has some performance advantages over the 243 with light bullets.

They do something new. They sell lol

The "same" cartridge that no one cares about, with arguably less going for it, typically doesn't. People need to care.

Kidding, mostly. 243 Win sells great. But opening up new options for common, heavy bullets and a supply of factory fast twist rifles chambered for them really helped. There was a market for it, its being catered to.
 
Once again, CGN Hunting rifle forum isn't the place to have a decent discussion on the merits of a new cartridge

New =

"Frankly, I'm sick to death" about hearing how whichever latest cartridge is "basically a...." or "Just a rebranded....."

why you gotta be hatin?

It is almost universally the case that newer cartridges have the capacity for longer, slipperier, higher BC pills.
It is also almost universally the case that newer cartridges make use of tighter rifling in order to stabilize said pills
It is also almost universally the case that they do so with less pressure, less throat erosion, and less felt recoil than their "Historical Equivalent", especially if you load them to try and compete with modern offerings.

Are there not at least a dozen common .30 cartridges? Did people whine and cry every time a new one of those came out?
After all, a 308 is just a better version of the 30-06. ;-)

Modern tap water is clean (almost too clean), abundant (round here anyway), and is often laced with beneficial substances.
Maybe it is just "rebranded" puddle slurpings but I am not opposed to it.

I do think it is a bit disingenuous for Hornady (or anyone) to brand any cartridge as the new WT Slammer or "Silver Bullet" for Elk. That's just crazy. Every game animal on earth could be ethically harvested with a 308 or any number of 100 year old offerings and if you want to shoot animals at 800 yards, I think you should work on your hunting skills and close the distance.

For me, new cartridges are about developing hand loads and mastering distance on steel. I don't even have a 6 or .22 CDM yet but the 6 is on the list and the 25 sounds cool to me.

When will the 7.62 CDM come out I wonder? I will take one.....

The 6 ARC is designed to operate in AR platforms. It has decidedly less cartridge capacity than the 6 CDM.
Likewise, the 6.5 Grendel is an AR platform offering, decidedly less capacity than the 6.5 CDM.

Both are great in AR's but even better in bolt rifles.
Not new enough??

What does it have to do?, your taxes?

No, Savage changed their 250-300 twist rate to 1-10, hmm, late 80s early 90s. I had one of them. Nice rifle, and much more accurate with heavier bullets than my 1920 was. - dan

You think comparing a new cartridge to previous similar cartridge is "hating"? Seriously? - dan
