CFX general tips and tuning

Hello guys.

I am new to the airgun world, so I don't know that much yet, but I am getting better real fast.

Can you guys suggest some things which I can do to my CFX to get the most out of it? I don't mean the most speed. I mean the most accuracy.

I know that this rifle is quite tricky to hold, and I also know that sandbaging it helps a lot.

I know that I must touch the rifle at the same spot every time, keep relaxed, etc... What else must I do especially to the CFX?

Also, what is an easy part to tune on it that will help accuracy?

Thanks a lot for all your help.
