I don't think that .300 win mag and .338 lapua mag having less damage at close range make sense, I know that there is the idea that of the round just zipping throught he body and not expanding would not make much damage, but maybe that is not how this works. everybody know that there are two types of gunshot wound cavity, temprary and permanent, there is a idea that low velocity rounds like pistol rounds the only damage that matters is the permanent cavity, but rifle rounds is different, it's known that temporary cavity from a high velocity rounds can do damage aswell because the bullet is so fast that it's enough to rip the elastic tissue. This is just what I think, anyway great mod!
