Itchy, if you go into forge world, stand on a rock out in the water, and just spam the pistol into the water, then do the same with the DMR. the pistol's spread is far greater than the dmr's at full bloom. I believe the fire rate it just higher, so by having more bullets in the air, you're more likely to get that headshot at close/mid range. It's a bit of luck I think, kind of like the H3 BR @ long range... but with Reach's better shot registry it just seems more consistent.
