Ok with the Long Range Awe Inspiring Gun, if we assume that your assumption that it's got a caliber of 58mm and that the damage of 7d-1 is correct then that means each scatter shot round is about 12.7mm which, if we treat it as shotshell, gives me a half damage range of 63.5 and max range of 1,270 and 0.67 die of damage. So it looks like everything adds up... except for the half damage range. So either Bill either accidentally use NP×10 for the half damage range or the Gun Design System rules for scatter shot had changed since High-Tech.

Now to figure out what's going one with the Long Range Gun's range with a full sized shot, I ran the numbers through Doug's spread sheet (I have the 2013 version). This got me a half damage range of 884 and a max range of 3,222. Doug's sheet does give different values for range then the formula used in house, but it is within the same ball park so I think it's safe to say that the range listed in Low-Tech is a copy past error.
