Simply awesome analysis! Though I only partially know the meaning of some of the terms...fleadermouse wrote:As a serious handgun shooter I decided to actually run the numbers on this an do some research on dart type projectiles
First the sectional density of a dart would be significantly higher than a traditional bullet . A 55 grain 3 mm dart would have a SD of 3.43 as compared to 1.57 for a 5.56 mm bullet thus the ballistics would be excellent.
As to the questions with recoil. I shoot 44 mag on a regular basis and can hit a standard chest silhouette at 50 yards all day long side arm one handed slow fire.
So I calculated the free recoil energy for my 44 load 1450 fps with a 240 grain bullet over win 296 25 grains: 21.20 ft/lbs
The free recoil energy for a 55 grain bullet at 6000 fps over 1 grain of powder ( I needed something to keep the program happy) is 11.78 ft/ lbs which is about the same as a full power 357 load. Definitely popping but not a structural problem for a normal human at all.

That's also where I'm thinking that Honor's range might be "way in the heck out there" if she wants it to be because she has to do a couple things to snap the weapon into a firing mode (which would presumably activate the fingertip camera,likely locking the structures inside her arm and finger into a long enough "barrel" for the dart, etc. We also know that she has and does practice with handguns AND her arm-hidden weapon.
I can picture one of her armsmen asking "what's the longest shot you can make regularly with that thing?" and her grinning and saying, let's go play! and maybe bet said fellow an Old Tilman on who wins the long-shot contest. The lady does like to win, after all.
