Input wanted for proprietary cartridge development, specifically for ccw use

[CubiCarry]

Hello everyone, I am here to get your input on an exciting new concept being developed called, as you might have guessed, “CubiCarry™”. The easiest way to explain the design is that the magazine space is better utilized by using rectangular as opposed to cylindrical cartridges (kind of like the difference between stacking boxes on top of each other instead of barrels) The inspiration was to maximize and optimize every aspect of the cartridge design to current day concealed weapons use. Although the CubiCarry concept is still in the early stages of development, we have found that by utilizing our patented design that the effective caliber of a given size platform can be increased by over 25%. What this means is that a pistol normally chambered in 9mm Luger (which uses a .355 caliber bullet) could become the 450 CubiCarry™ (utilizing a projectile measuring .450 across, as well as an increase in case volume) with no increase in platform size (for you “bigger is better’ folks out there we also have a 500 CubiCarry™ variant based on the 40S&W size platform, as well as a smaller version based on a 32ACP). The design is also such that a weapon with a CubiCarry chambering could also be made to fire conventional ammunition with a simple change in barrel, magazine, and recoil spring. The current plan is to optimize propellant charge and bullet construction to meet the FBI and IWBA standards for both the bare gelatin and denim/ gelatin test, without relying on expansion. At this time it is anticipated that CubiCarry cartridges will be offered by existing manufactures (such as Glock, Smith & Wesson, etc.) and so we have no speculations on a proprietary pistol design to be used. Hopefully you are excited as we are, and we appreciate any and all input by you, particularly in the areas listed below. Thank you!

-What are your initial impressions of the idea of a “cubic” bullet?
-What degree of accuracy would you find minimally acceptable at 7 yards?
-What single element dictates your choice of caliber in you concealed carry weapon(s) the most?
-What do you value more; faster follow-up shots or more foot pounds of energy?
-How concerned are you about bullet performance after passing through barriers such as glass, drywall, etc.?

Well, since you asked,:

"What are your initial impressions of the idea of a “cubic” bullet?" It strikes me as a gimmick, nothing to be taken seriously, an interesting idea to kick around but not something actually worth pursuing.

"-What degree of accuracy would you find minimally acceptable at 7 yards?" Same as I expect from a firearm firing regular rounds

"-What single element dictates your choice of caliber in you[r] concealed carry weapon(s) the most?" There isn't a single element, its a balance of various factors. I want a 12 gauge semi-auto shotgun holding 10 rounds with the recoil of a .22 that fits in my pocket and weighs under 12 oz loaded. But since I can't have that, I have to balance various factors. Concealabilty is my most important consideration.

"-What do you value more; faster follow-up shots or more foot pounds of energy?" Between those two, faster follow up shots.

"-How concerned are you about bullet performance after passing through barriers such as glass, drywall, etc.?" Absolutely and completely unconcerned. It is a factor that doesn't ever enter at all into my considerations in choosing a concealed carry weapon.

Good luck with your project, but I'm afraid that I have no interest in it.

Thanks for the response TrapperBob, I should probably clarify that the projectile is cubic at the base and then transitions to a more conventional profile toward the nose. We understand that ccw's, like everything else in life, is a compromise. The question is simply meant to extract what factor of those compromises carries the most weight for you. For me it is size of the platform, I would love carry a .45 but my body frame and lifestyle won't accommodate anything larger than a 9mm. That's where the concept really shines; it allows for a larger projectile without increasing the size of the weapon. That isn't as large of a concern for some as it is for others but its a great advantage to those for whom it is. If ever you are curious, Link Removed has a bit of information on it (who knows, at the very least it will be worth a good laugh). Thanks again!

I think I am confused on one point. I understand the concept of the cubic case, but will the bullet be cubic as well? Are you going to get a cubic bullet to spin down a rifled barrel? Might happen, but I'm just trying to picture it.

why fix something thats not broke ?

 

[CubiCarry]

As of right now we are planning on testing non-rotating projectiles. Given that the distance is relatively short (25 yards and less), we have good reason to believe we can achieve satisfactory accuracy. stevie3x, I will be the first to say that there isn't anything necessarily "broke" with today's ccw's, really we live in the golden age of them. That being said, I don't think there is anything wrong with exploring possible improvements. More power in a smaller package (which has everything to do with efficiency) seems to be the pursuit of most of the industry, and so at least the exploration of this efficient concept seems somewhat of an inevitability. We really do love the input; others who are excited about the concept provide a lot of motivation and those who think its a horrible idea can at the very least point out possible problems. All in all its great.

I see nothing wrong with fixing something that isn't broken, as long as the "fix" is an improvement. Cartridge manufacturers are constantly coming out with "new and improved" defensive rounds, when we have an abundance of great ammo already available.
I kind of question how accurate a square, non-rotating bullet can be, but I'm interested in seeing results. I'll bet it will tumble like crazy.
