30 super carry

[Magnumite]

A 1250 fps 100 grain 30 caliber bullet is basically a castrated 30 M1 carbine round. Just a perspective approach. Lop the 30 Carbine case off at .910” load to pressure and you’re at the new 30 round in .308 caliber. Just sayin…

Doing simple math, and I know wound ballistics is not simple math, the .571” x 14.5” hole will leak more blood than the longer .531” x 15.5” hole. This could be interpreted as the 2 extra rounds are needed to neutralize or be an advantage (I agree, not likely). Still, 10 rounds of each demonstrates greater wounding potential for the 9mm.

With these ballistics it is assumed at those depths of penetration may exit the target, yielding even greater wounding for the 9mm. Again I agree exiting the torso likely won’t occur because of other factors involved.

Power factor for the new .312” is 125. For the typical SD 9mm loading in 115 gr and 124 grain bullet weights is 138 - 146. Momentum goes to 9mm.

The 100 grain .312” bullet is heavy for caliber. Typically, those bullets are 71 grain projectiles in 32 ACP and 85 grain for 7.62x25 (which has a larger case capacity). The standard for caliber weight for 9mm is 124 at 1175 to 1250 fps and many SD loads are in this bullet weight.

Section densities for both is .146 for the new 30 and .141 for the 124 grain 9mm. Very similar SD’s so similar penetration.

I see the only advantage to the new round is capacity. Nothing wrong with that. But I wouldn't be trading a good CCW 9mm for it.

The key is they are achieving 9mm energy, sectional density, and penetration/expanded diameter with a smaller diameter case. On it's own probably good for 20% more capacity, but in the long run allows slimmer grips and even smaller doublestack CCW designs than the current crop of P365, hellcat, Shield plus. Handgun bullet designs are so good at turning energy, and sectional density into penetration/expansion that this is the next step. Of course FMJ bullets kinda defeat the purpose outside of practice.

With good bullet designs and heavier/higher SD 9mm ended up getting really close to 40S&W gel tests, but with better efficiency and less recoil, this 30super kinda does that getting close to 9mm. Maybe one day they could produce an even smaller diameter bullet at 9mm OAL with sufficient material/energy to expand and produce these numbers in even smaller calibers, but not there yet. One thing that could be intriguing is hydro-dynamic expansion designs like Lehigh's extreme defense that funnels jets of soft tissue in a way to produce similar wounds to expanding ammo without expansion in a solid copper bullet, therefore not requiring the mass or diameter that a larger caliber requires. With that tech, could potentially have a really small/light and compact cartridge running rifle pressures at very high velocities still producing light recoil with high capacity, but able to produce 9mm or better test result.

Also, Love that they went with "30 super" for the name and not some metric BS, because 'merica, might need a 1911 in 30 super to add to my 38 and 45 varieties

^^^^ Yeah! ‘Merica!

I was just putting those comparisons out there.

I was thinking as I typed my last post… Para 9-18 would be a 30-21 with standard base plate. With the +3 setup I have, that would be 25 shots in a mag. Easily one 50 round box of ammo in two mags. I can just imagine a 2011 platform and USPSA legal mag.

As I said in the other thread, , I would buy into it if they make a platform similar in size to my Ruger LCP II.

One of the specs few really pay attention to is the 50K PSI pressure spec. Not sure if they are using rifle primers or what, but it's basically loaded to 9mm major pressures, some pistol primers hold up, some flatten out and can cause jams. Figure this has a lot of advancements beyond the 120 year old 9x19, and has a lot of advantages, provided firearms are designed around it instead of just rolling spacer lines on 9mm mags and slapping in a different barrel/breech face. Ideally this could be epic in some formats, a small pistol with a really slim double stack like LCP size would be the most useable. Of course there are a lot of designs around for 3 row mags that could probably fit 10 more rounds (like flush 27rd mags in a GLOCK 17) instead of just3 or 4 in a doublestack. Probably the best would be a PCC, enough pressure to allow gas op or even delayed blowback it should have light recoil, tons of capacity in a reasonably sized mag(like 50rds in a mag the same size as a GLOCK 33rd) and could use 9mm or 30cal suppressors. Even better if they can cram a heavy 130gr+ bullet in the tiny case and make subsonic loads for it. On the surface it seems to have the ability to do what 9mm can do with heavy bullets, fit in 380 sized pistols, and could even get in on 5.7FN's territory with PDWs and fast loads with light Lehigh extreme type bullets.

Do you mean three columns? How do they accomplish that without everything just going wherever it wants and eventualy binding up?

I tried some google searches but didn't see anything resembling what you seem to be describing.


PS sorry for the thread diversion.

It has my attention. Want to shoot it

Small pistol primers. Pressures are MUCH higher than 9mm. Any kind of blowback action is not going to work. My guess is that the chamber wall thickness will require the same OD as 9mm. I did not at first realize that the bore size is exactly 8mm.

Most micro .380's have been locked breach for sometime. If they can fit the 30 carry into the footprint of a Kahr 380 or Ruger LCP II, I will jump on it.

Those pressures are impressive. This may beat 9mm as a HD round in a PCC

How many you figure we can fit in a G33 mag?

Yeah, i did the same search and found 4 column AK mags, but nothing 3 column. Keltec uses 2 staggered column mags in it's new hi cap mag. There is a diagram if you scroll down. Maybe that would work? They have the patent though.

There were a cpuple weird european mag designs in the 80s. Helical, and 3 row offset. Think it was HK or FN that was working on it. Basically rounds stacked is 3 rows, the problem was the 2 outer rows would bind up in the mag as they try to feed at the same time. The answer was to offset the single feed taper to one side. There are 4 stack, where basically 2 stack mags are next to each other with a divider, and helical where the ammo column is wound inside a tube. With skinny bullets, you have room to stack ammo in weird ways

Considering the crazy variety of 9mm pistols that seem to constantly appear from manufacturers I have recently been contemplating going back to 9mm instead of my go to 45acp. I am a simple guy, big bullet means big hole. I truly believe shot placement is WAY more important than how many you fling through the air, but can admit I can get multiple rounds off a little quicker with a 9mm, a little quicker.

Then 30 super carry (cool name that implies some sort of super hero characteristics). Oh great.......... I've never been one to go after the new shiny thing and want to see how I think does for a while. I'd like to shot one, esp at a plate, to see what kind of energy it has.

Speaking off, the big reason I haven't went 9mm from 45 you ask? Steel plate test. Plate swings with the 9mm, plate and stand almost fall over with quick 45 hits. Can't argue with the energy. Also heard to many stories about badguys taking multiple 9mm rounds and still being badguys for awhile.

Now if the 30SC feels like a 9 and hits like a 45 I'm sold........but I won't hold my breath.
