  • Input wanted on proprietary cartridge design, specifically for ccw use

    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.?

    Sounds a bit dangerous.
    Getting shot hurts! Don't under estimate the power of live ammo. A .22LR can kill you! I personally feel that it's best to avoid being shot by any caliber. Your vest may stop the bullet, but you'll still get a nice bruise or other injury to remember the experience.

      As someone who carries a proprietary pistol round on duty, let me say this:

      While your concept is interesting to say the least, I think cost is going to be a major inhibitor.

      Good luck.

        I think this is akin to the opposite seatbelt design.

          Thank you all for the replies. Haha, the goal is for it to be dangerous, just for the bad guys. reils49, cost is definitely a major factor. One thing we have done to help offset that is worked in a convertibility aspect that allows conventional ammunition to be used in training, saving the more expensive ammunition for duty use. I realize this isn't a cure-all, but it helps. There is quite a bit more information on www.cubicarry.com for those who are interested. Thanks!

            Come back in five years after you have proven it works AND ALL the firearms manufacturers, DOJ, FBI, etc, have tested and approved it, AND the ATF has ok'd it...

              The problem I see with changing out a barrel and using a regular 9mm vs your cube 9mm is the recoil will not be the same and the trajectory of the round will be different. This can cause issues with training.

              I currently am issued 357 Sig and run into this problem. Practice rounds are too expensive so i have to train with a 9mm barrel. Changing rounds changes the way the gun shoot. When you change the way your gun shoot then that makes training not as effective.

                An example of WHY when I carried my 686, I trained with .357 ammo, not .38. You ALWAYS shoot what you carry.

                  Another problem I see with this design is the double stack mags will be huge. It looks like you are working with the 32ACP, 9mm, and 40 S&W. 2 of those 3 are primarily used in double stack mags. In order to fit 17 rounds into a Glock 17, the mag will have to be wider to accept the cube rounds. This will make the grip of the pistol way to big. I would like to know how you are going to overcome that issue?

                    Magic....

                    But of course the manufacturer will adapt their weapons to this amazing ammo.

                      I wonder about the pressures in a rectangular cartridge versus a cylindrical configuration.

                      If it was a viable concept I imagine it would have been adopted years ago. I'm hard pressed to imagine square is better than round for a whole mess of reasons.
                      Rule #1 - If it doesn't change supper it's not worth the worry.
                      Rule #10 - YOU ARE NOW THE MINORITY. This country is no longer the one your parents knew. You will not be able to understand it. You will not be able to change it. You must learn to live with it.

                          You've found a solution to a problem that doesn't exist.

                              The ballistics of a square bullet out of a smooth bore, square, short barreled pistol.....even at 7 yds. it would be spray and pray. I don't see it.....but good luck. How accurate are bean bags?
