Sometimes I like to shoot my gun a little lower (friends say I shoot from the hip but not that low) so that my hopper's really not above my head, I think it's like that in my avatar but I'm running so that doesn't really count. I find that instead of trying to hold your gun next to your face like I used to do, it could feel more comfortable holding it so that your barrel lines up to the bottom of your face and your shooting arm's more relaxed. It's kind of hard to explain, and it depends on your gun setup too. If you're using a drop you might want to try your gun without it to see if that feels better.
