I don't know if this is an SA issue, but since I was running SA, I am posting here.
Anyway, I was playing on RAWHIDE with Dadamungo, Floid and Chainsaw, and I noticed that I was getting kills better from far away, even with the lowly default Remington pistol, and I was having a very hard time getting kills close up, even with the Peacemaker. I commented online that it seemed almost random, and Dadamungo said it seemed that way to him also. (Don't want to put words in your mouth, Dad, but I remember you agreed in a general way.)
I'm no sharpshooter, as you know, so if I was getting kills with one or two shots from 'way down the street, it is surprising.
