Newest Caliber Ever?

[.455_Hunter]

Take a look at the 8mm Roth-Styer for an example of what a cartridge of this class could be like. Pretty good ballistics for 1907, and could be enhanced a bit with modern powders.

With the SHOT Show only a couple of weeks away, this may be one of their introductions there.

At least maybe there will be details on the cartridge.

I can see this being a niche caliber/gun if the following conditions are met:

1. Must be available (well, duh!).

2. The gun should be easier to rack and have low recoil. This is for those people with hand-strength problems and things like arthritis. There are threads on this forum about people working those issues. This will give them an option other than going to .22LR.

3. A MODERATE increase in power. Trying to "magnumize" it will defeat the purpose. Keep it subsonic.

4. Quality. If S&W can't deliver a gun that works out-of-the-box for people who don't shoot that much, there's no point.

An additional factor: there may be some markets around the world where the .30-ish calibers are the only easily available options for civilians.

Your thoughts?

Now: on the totally off-topic and probably unrealistic side, I'm already dreaming of .22 target auto formats with this cartridge, just for the heck of it!

I saw one ad that claimed 1200 fps. But other than that I can't find any specs or even a picture this thing.
IDK, I've always been kinda fond of the various .32 calibers. But until more info is available, I'll withhold judgement.

Yep. The rumor is a 100grn bullet moving at 1200fps.

Another rumor is that Remington as well as Federal will produce the ammo.

Neat, but smallbore/high velocity cartridges usually demand longer barrels to be efficient.

We're not getting rid of the 9mm and .380 until we develop handheld railguns or energy weapons...they cheaply and reliably put holes in bodies at realistic pistol ranges.

 

[steelslaver]

A necked down case does not make sense because the case diameter is the main limit to capacity, magazine or cylinder. A 9mm length case and a short bullet so it has about the same overall as a 380.

a 1200fps 100gr has 267 ftlb which is in the 380 ball park

I am not a semi auto guy myself. But I do find it interesting.

I do have a Alloy J frame 32H&R and in light weight clothing weather I am as comfortable with its 6 shots as I am with my 37s 5 shots in 38 special.

But, it isn't all about need. How many guys here only have guns they need???? LOL

I had 3 6mm Remington rifles, a 25-06 and a 308. Yet, I built a 6.5 Creedmoore

A thread on another forum has pictures of the cartridge, including the dimensional diagram and a ballistics chart.

 

[Paul in Nevada]

Federal lists a 100gr HST @1250fps.
Supposedly S&W will offer a 30 Carry Shield Plus as well.
If the Shield was 15/17 rounds it would be interesting. I think a little carbine the size of a 10/22 would be neat.

 

[malph]

How longer before Ruger, Keltec and a few others come out with guns chambered for this cartridge?

3. A MODERATE increase in power. Trying to "magnumize" it will defeat the purpose. Keep it subsonic.

I agree. At most it should be as powerful as a 380. And even then a 95 grain, 30 caliber bullet at 900 fps would generate the same recoil as a 95 grain, 9mm bullet at 900 fps.

If the posts I read about it being a 100 grain at 1200 fps are right it would have 319 ft-lbs of energy, close to 9mm. It would still have the advantage of greater capacity but would have close to the same recoil as a 9mm.

More capacity is good and companies like Magguts stay in business increasing the capacity of magazines by a round or two. But I still think a cartridge designed for people that want less recoil makes more sense than a cartridge for those that want more capacity than 9mm can provide.

I bought a Sig P365 primarily because it is similar in size and weight to my Glock 43 but holds 4 more rounds. So I might replace my 9mm 365 for a 3version that held a few more rounds of a hot 30. But I would be much more like to buy a weaker 30 caliber version if arthritis someday makes shooting even a 9mm difficult.

ETA: I just saw the post below this one. So much for my prognostication abilities.

$32 for a box of 50 FMJs, I'm feeling left behind.

At those prices, it's not for plinking, that's for sure.

The Remington and Blazer Brass will hopefully be a bit cheaper.

 

[CH4]

I doubt this silly cartridge will last as long as the 45 gap. Perhaps CZ needs to buy Smith too.

 

[44wheelman]

Buy it now, put it up…and in 25 years…collectible. Anyone remember the 41ae?

Still trying to find a 9x23. Missed out on a Springfield custom for $2k, and kick myself. Then I think, really, 2k?

The 327's are hanging on, 357sig is not as obsolete as I thought I'd be given the price, 10mm has actually gotten popular again. 41 rem mag reached cult status.

We'll see how the marketing goes…should be fun.

 

[hkcavalier]

With what I said earlier aside, it IS interesting...

Seems we've all figured out that big calibers that blast away hunks of meat don't stop fights immediately. CNS hits...even with a small bullet...do. So give yourself more chances to get those CNS hits with a small, high velocity bullet that penetrates well.

 

[Dave Lively]

It will be interesting to see what the pressure limit is for this and if it causes problems. Getting the same power with a smaller diameter bullet requires more pressure and 9mm is pretty high in terms of pressure.

Found this interesting....

[robertrwalsh]

So these appear to be a straight-walled case designed for the .30 bullet. It should look very much like a short .30 carbine case loaded to COL the same as that of a 9mm. Should do the job if you can hit with it. The old .30 Mauser was not a slouch and the hotter loaded .30 Tokarev rounds were even nastier.
