Umarex Ruger Blackhawk .177 break barrel

Is anyone else shooting one of these? If so, I have a few questions.

1. what pellets have you found to be most accurate?
2. have you rescoped it and if so with what?
3. have you tried to quiet it down and if so, what have you done, and what results?
4. what do you use it for, target, or pesting or both?
5. do you have other spring piston rifles, and how does the Ruger Blackhawk compare to them?

Thanks to all that have replies to share.
