The level of sniping in Halo and Destiny are so much different. If you're good at sniping in halo doesn't mean that you are good in Destiny. Haha, I wouldn't practice halo for destiny. However I agree, I'm not very good at sniping in destiny but I am decent in halo so I have no idea XD it could also be a final round or random bullet bonus damage too so don't feel too bad.
