I'm sorry it took so long for me to post as well - it's frustrating since it's something so simple and enjoyable to do, yet I kept putting it off.
On another note, I feel like doing a facepalm for another reason entirely. I suspect that I had messed up the weapon scales when working on the M3's weapons - I haven't had time to do the comparison, but my guess is that I accidentally Gundam-sized them so their bore is far too large. The M3 is 7 meters tall, and the shotgun is 300mm, while the rifle is 75mm for an example. The best thing to do is to retcon I think, since keeping it at its too-large size would negatively impact how things would go IC. If it were played realistically.
An example of what I mean can be seen with the 50mm on the Mindy/Daisy - the scale is wrong with 50mm rounds, so its magazine is the size of a gallon milk bottle since it holds 18 shots.
