Dragunov Combos

Pretty repetitive question but anyone got his optimal best combos. I find some online stuff but either have no damage number so I can't tell if it's good and some others I find online, I can do more damage with an easier combo. The reason why I'm asking is cause the combos I do have no CDC~u1 in them and I feel like I'm not using him to the fullest. Thanks guys.

are these good combos https://www.youtube.com/watch?v=ngqMdzG7Tsk
