I shoot both ways, but only really accurately right-handed. I've learned a lot shooting left-handed that has helped me with my shooting in general. For example, since I'm weaker shooting left-handed, I'm more aware of the necessity for bone-on-bone alignment, whereas shooting right-handed I tend to get a little sloppy and open up more. For some reason, I also noticed that my head was drooping shooting left-handed, so am more aware of keeping it upright. Any little error seems magnified shooting left-handed, which helps me to shoot better right-handed too.
