No I haven't. I wasn't even aware of it, but I just looked it up. Unfortunately, it's not free software.Have you ran the Quickload performance projections?
Hmm. It's auto-shrinking.

I don't think your proposed ballistics are going to work out.
A related issue is the cost/benefit analysis. Analysis of real-world shooting (with handguns) shows a sharp drop in effectiveness when you go from a 9mm/.38 caliber bullet to a .22/.25/.32 caliber bullet at handgun velocities and energy (The data did not include magnum .32 calibers; insufficient data.) No, we don't know why. So the potential gain of a couple of extra rounds in the magazine has to be balanced against the very real possibility of a significant drop in real-world performance.
Also- the choice of 6.8mm specifically is almost a deal-killer on the face of it; you not only have to make a new cartridge, but you would need a complete new line of bullets to fire from it. It would be hugely more likely to succeed in .32 caliber, where there are already a wide variety of bullets available to load in the cartridge, and you will not really lose anything in magazine capacity. I was actually thinking about a similar concept called.32 Super Auto- a straight-walled 7.65x19mm. My thought was to take advantage of bullets designed for .32 H&R Magnum and .327 Federal Magnum.
Ah... don’t ruin it for him... he was looking to convince a novelty company into developing a SAAMI cartridge based on some Visio mock up... I was hoping he’d at least go down some of the most basic wildcatter steps to assess potential performance of the design... give a man vs. teach a man, as it were... ruins the fun if you point out there aren’t any fish in the bathtub before they even get started!
I tend to think the development of a new cartridge should be any gun company’s last resort.
New defensive Cartridge development has a history of producing expensive and sometimes unobtainable ammunition and guns that sit on shelves for years.
I took a tragic massacre to put the 5.7x28 on the radar.
Why 6.8? Is that a width that can maximize capacity in a gun such as the PF9?
A European company was showing a concept prototype similar to your concept at SHOT in 2010. It garnered very little interest, sadly. Part of the problem is that introducing a new cartridge is always an uphill battle, and acceptance is often slow because people don't want to be left with an 'orphan' gun/cartridge if it doesn't pan out.
This is where I was hoping someone here could help out.I don't think your proposed ballistics are going to work out.
Honestly I think there are plenty of good cartridges out there to choose from.
This would be an uphill battle to nowhere at best.
The auto pistol version of the .327 Mag would be the 7.63 X 25 Mauser or Tokarev. It drives an 85-86 grain bullet to between 1,400 and 1,500 fps..
