Well. I've been running some test with a friend to check damage charts for the Sniper weapons and tomorrow I'll see what I can do. Some damage charts are the same in PC and consoles, other aren't, take the SMG as an example, it's more powerful on consoles.
If you'd like to partake just send me a message to my Gamertag, which is the same as my username and I will pretty much stop whatever I'm playing and I'll get working,
You can also run test on your own with other friends, but make sure to post your results in the following thread over the Steam Forums.
